Variable Monthly Usage With Maximum Limit?
May 29, 2014
i am working on model where customer is billed based on usage of the equipment. Usage is measured in cycles per day. Assuming there are 30 Days a month. i am trying to build a spreadsheet where if i increase or decrease the monthly usage it automatically update the sheet. Remember there is limit on maximum number of times an equipment can be used.
Like for Example
Maximum life of one equipment. 3000 Cycles
Daily usage : From 1 cycle per day to 10 cycles.
Monthly usage = 30 Days * (daily usage)
Now the problem is each month new equipment is leased. so i have to keep track of each month's equipment how much it has been used and how much left. I have attached the example spreadsheet.

In the attached sheet, I have logged my gas energy consumption (kWh) from 2006 to 2012. I want to analyse my relative consumption over time, on a monthly basis.
However, the bills have been generated by different suppliers for irregular periods (eg. 10-May-2006 to 24-Jul-2006, or 23-Feb-2010 to 6-Mar-2010). So, how can I re-tool my sheet to arrive at rough figures that can be allocated against each month?
Or, if there is no dependability about that method, formulae which allow for effective comparison over time? Let's say, daily?

In a macro I am writing, I am trying to use the data stored in a variable inside a formula. Specifically, my variable holds a string that represents the title of a specific sheet in my workbook. I am trying to put this variable into the count formula to be used as the sheet location.

What I'm trying to do is get the MAX function to return a value, but that value needs to come before the values reach zero. It's a cubic equation that basically starts, at the beginning of the data range, under 10 then hits zero and ends up near 30 at the end of the data range. The end data range max doesn't matter to me if the data range hits zero along the way. Is there any way to make the MAX function stop at a certain value, or is there another function that could accomplish what I'm trying to do?

I am in the process of creating a template in excel with certain restrictions on the information that can be added to it. I've hunted several sites and forums to try and find a solution but find it difficult to see the best ones for my project. The template is roughly made up of say 10 references to large boxes, each box can hold smaller boxes. The smaller boxes vary in size. For example the large box is 60 inches long smaller boxes vary between 20 inches and 40 inches, can excel be made to tell me an error if i try to put 2 x 40 boxes in columns refering to 1 of the larger boxes as it exceed the maximum length of 60 inches?

Given this formula =(H2+( SUM(K53:DB53))) which simply takes an existing value and adds to it the sum of a series of values. I am happy if the value returned is any number less than 28. However if the value returned from the above formula is >28 I want the number returned to be shown as 28.

I was wondering if there was a way of reducing the maximum characters allowed in a cell reference.
I am creating a form which Bank details need to be entered and would like to only allow a possible 16 characters.

I am working on a project to import cellular phone usage data from Sprint into a workbook.
All cells in Column A are blank. Column B contains 1 instance of the cell phone account #, followed by dates of calls made, which continues until the next cell phone account # appears, and it’s calls made. The # of calls made obviously varies per account #.
The dates are in date format. The cell phone account # is in text format and is formatted with blue fill.
I need to copy the cell phone account # into column A for each line that has a date value in ColumnB, but the value copied must change when it reaches the next cell phone account #, so that the calls are matched up with the cell phone account # and can be imported into SQL.
Acct #
Date
Time
City Called from
State Called From
Called #

I have a sheet with a hierarchy of operating units in a column, with DirectX checkboxes next to each (used a VBA script to auto-create the checkboxes ).
The checkboxes go from D5:D147, so 142 checkboxes. They are named checkbox_D5, checkbox_D6 all the way to 147, so checkbox_[Column]&[Row].
Based on a True/False value in another column to the right (BA or column#53), I am hiding specific rows. Just to give a sense, if a checkbox for a Level 2 hierarchy is clicked, I have some formulas to determine which Level 3 rows will be shown by putting a TRUE in column BA. For sake a speed, I created these to only run for 30 rows per click (that's the most that would ever change on a checkbox click).
I did not know how to do it any cleaner, so I created 142 of these:
Code:
Private Sub CheckBox_D5_Change()
Dim i As Long
For i = 5 To i + 30
[Code]....
It works OK up to checkbox_D23 or 24, but excel seems to reduce the number of rows it goes through for each checkbox below that, with checkbox_D31 down doing nothing. I read somewhere about a 32 form item limit, wonder if I'm hitting that.. Cleaner way to do this vs. 142 instances of checkbox_XX_change() events?

I am now working on an excel spreadsheet which will automatically update every day so that one row will be added on the top of the sheet everyday.i.e.
A1 Date Price
A2 (New row added,date) (New row added,price)
A3 16/1/2013 5.5
A4 15/1/2013 5.6
A5 14/1/2013 5.45
... ...
Assuming that I am looking for maximum value of the column "Price", since max() cannot be applied to variable range, is there other method I could useto look for the most updated maximum value of column "price"?

I have been trying to determine the maximum/minimum value and additional count from a variable range which then I can use to subtract the first data of the range; I have been able to do that for a fixed range but not a variable one.
I have Column A with random positive numbers.
I have Column B with random negative numbers.
I have Column C with random numbers.
I have Column D with random numbers.
I have Column E with random 0’s and 1’s.
I have a set of 1600 cells of numerical data on each of the columns and there will be times when the random 0’s and 1’s from Column D will have appear repeatedly before changing to the opposite number, fx, I will get 7 nr. 1s before I get a 0 (zero).
I have been able to obtain the values in 2 cells within a fixed range:
If the last 8 cells in Column D have been “1” then I do:
F1=MAX(A1:A8)
G1=INDEX(C1:C8;MATCH(9.99999999999999E+307;C1:C8)) ---(Which provides the first number of the range in Column C after Column D has changed from 0 in D9 to 1 in D8)
H1=(F1-G1)
If the next 3 cells in Column D have been “0” then I do:
F9=MIN(B9:B11)
G9=INDEX(C9:C11;MATCH(9.99999999999999E+307;C9:C11)) ---(Which provides the first number of this range after Column D has changed from 1 in D12 to 0 in D11)
H9=(G1-F1)
Additional to this, the COUNT has also been challenging since I want to obtain in Column I, the COUNT of repeated 1’s from each range of 1’s in Column D; and also in Column J the same but for 0’s.
Fx:I18 (size of the range of 1’s originated from D1:D8)
J93 (size of the range of 0’s which consist to be the next range before 1’s were originated)
I12X (size of the range of 1’s which consist to be the next range before changed to 0’s)
However, that only works for a fixed range and continuous updates are made.

I have a table of yearly totals for the amount spent by x. I also have a growth rate for each month so for example in 2001 in jan the growth rate might have been 0.3% and feb 0.5% What I want to do is for each month based on the growth rate and the total produce a value for each month which sum to the total amount. It's also important to note that it restarts each year.

I was hoping that my formula would give me the count number based on the Maximum time (latest time) and the Name field...My result is a 0 instead of 62 (the correct answer).
=SUM((Download!$H$2:$H$10=A4)*(Download!$D$2:$D$10=MAX(IF(Download!$H$2:$H$10=$A4,Download!$D$2:$D$1 0)))*Download!$I$2:$I$10)
Would a Index/Match/MAX function be more efficient?

Look in Column E and find the MAX value. Once you find the MAX value, (let's say E27) display the date that's in C27. I bet this is really easy but I've been screwing around with it for over a half hour and can't get the correct result.

I have two columns of data. The first column is the 'type' and the second column is the 'value'. I need to find the maximum 'value' for each individual 'type'
The 'types' are not necessarily next to each other and the data cannot be sorted to do so.
Example:
type value
A 15
B 6
A 21
C 7
B 13
I need to be able to say the MAX for 'A' is 21, the MAX for 'B' is 13 and the MAX for 'C' is 7.

This seems like it is pretty easy but for some reason it is being goofy for me.
I entered this code to check it.
IF IsEmpty(Range("A1")) Then
msgbox("Yes, It is empty")
Else
msgbox("Not empty")
When it comes up I always get the box with "Not empty" even though I havent typed anything in the cell since I have created it. Even tried Clear Cell. Basically what it is for is to check if cell A1 is empty and if it is, it will create a Data header and if not, it will find the first empty cell and continue inputting data.

i have seen lot of formula especially sumproduct where "--" or "-" is used. i understand it is used for giving the conditions when the column has text or dates to be retrieved. But what decides two minus or single minus or no minus to be used.
If somebody can throw some light on this will be really helpful for my excel

done some VBScript spreadsheet reporting involving basically inserting data and some formatting.
I need some advice on what approach to take with Excel on my current project. The basic goal is to scrape project requirements off a word doc and load them into Quality Center (a test management tool from HP, henceforth referred to as QC). I have an hta/vbs process that offers the user choices gleaned from the QC API, scrapes the word doc, and creates a spreadsheet with a row for each requirement and a column for each property a "requirement" has in QC. These values are a combination of data from the word doc and values selected by the user in the preceeding hta interface.
The reason for this Excel step in the process is that all the values chosen up to this point are generic for the entire project. But there are a few properties that will be requirement specific. So all the info is collected in Excel and the user is to then go through each row and choose the "target cycle" (which I pulled off QC earlier in the process and display in Excel as a dropdown list). The "Platform Folder" and the "Module Folder".
Ok, so with that backround, here is my quandry... In the hta interface the user selected all the "Platform Folders" the project will have requirements in. These are then presented in a dropdown in the Excel, so the user can choose which of these Platform Folders this specific requirement should be loaded into. What I need to do is then have the "Module Folders" to be a dropdown that is dependant on the "Platform folder" chosen.
This is difficult enough for me, creating a dynamic dependant dropdown that will be replicated on each row. I don't know exactly how to do this but feel I can probably figure it out with all the help offered on these MVP sites.
What I can't figure out is where to do this. Should I set up the lists, formulas, and control code dynamically? Can these dependant list derive their values from comma delimited lists (like I did the non-dependent lists) or must they be in a worksheet? The only way I see to make the dependent dropdown work correctly is to have it run off a worksheet event. Can worksheet event code be applied dynamically or do I need to have a "template" type workbook containing the code in the application's folder and use that instead of creating a new workbook at exe time? I still have to write the upload into QC code, and that will probably be a macro that the user will have to install into their personal.xls. Can the dependent dropdown code be installed in the same way even though it needs to be event driven? Another aspect is getting the data for the dropdown. I can either get the lists earlier in the process when I already have a connection to QC and pass it along, or I can connect to QC from Excel and get the values dynamically. I am assuming passing them in will be more efficient.

We have designed a data collection program in excel which use's userforms for the data entry and form printing. There are 20 userforms, each with a "Next" button which hides the current userform and shows the next userform. The first "next" button has a copy and paste code which copies a today() statement and paste's it in a different cell to record how long it took to complete the data entry. We are able to go through the program once, but when we try a second time it freezes and the cpu usage goes to 100% resulting in us having to End Task.

I'm using a Dell P4, 1.6Ghz, 512Mhz of memory (Win2K & Excel 2003), and it's bogging on spreadsheets that aren't that big and complicated (compared to thing's I did years ago, in the days of 386's and Win98)...
It hits the 100% CPU usage and stays there for minutes (especially when saving) on files that are only around 2M in size, yet it's not using much of the memory...
Spreadsheets large or small seem to have little effect on how much memory is being used... is Win2K allocating a fixed % of total memory for Excel to use?... can this be changed, so Excel gets to use more of the available memory?
I've been cleaning up and redesigning my spreadsheets to make them more efficient, but there seems to be a disconnect between my hardware specs and Excel's performance with files that aren't that big ~:-/
Disabling my antivirus software (Nortons) prior to saving, seems to speed it up a little, but this is not something I should be having to do...

how I have the data arranged... What I need to do is for each type I need to be able to calculate usage, so I will need to make sure it is subtracting say COKE usage the week of APRIL 1ST where beginning inventory on april 1ST was 99 and on April 7th the invnentory was 72, of course the usage is 99-72/7 will give me per day but I need the formula to be able to know which date will correlate to know which inventory to subtract from... So each time I add a new inventory in the sheet it will always be able to find where the data is it needs to subtract from to get the proper usage... Of course do this without manually entering the usage each week...

I have a worksheet where the user selects between two option controls, which are mutually exclusive. when they toggle an option, a user form pops up, depending on which option they selected, and askes them for a number, which is used in a calculation elsewhere in the page. The user form has a cancel button, in case they decide to back out. If they cancel, I want the option buttons to reset back to their original state.
The problem I'm having is that when I code it, if you select cancel on the user form, it causes the option to revert back to it's previous state, but that triggers the selection of the option again, which pops up the form, making a neverending loop! Is there a better way to do this? I tried it with a toggle button, with the same results.

I have created an excel tool w/ A LOT of macros in it, and the tool "speaks" to the SQL server (downloads data from it and uploads it back). My big problem now is that every time I run any of the VBA code the amount of RAM that is getting allocated to Excel (2007) is increasing - I am checking it in the Task Manager. So if I work for a long time without closing down Excel - my entire RAM is getting consumed and the system slows down, and sometimes crushes.
I was wondering if there is a way in VBA to clean up memory that is used by Excel.
Do you have any hints? I am using extensively 3 things - screenupdating off; displaymessages off, and calculations off. But this speeds up Excel but doesn't reduce the memory usage.

basically im setting a range type variable to be the a column of data from a table that is on another sheet but in the same workbook. im wondering if im supposed to get rid of certain variables i have created...especially in an instance like this, where the variable seems to be more of a reference to the actual table data.
Dim curtzeNum As Range
Set curtzeNum = Worksheets("RawData").Range("Table3[Curtze_num]")
should there be an erase statement for these at the end of the sub?

I was reading in the sticky post about the new version of Excel that is due out this year. One of the improvements listed was the increase of usable memory by Excel from 1gig to the amount of Windows memory. In reading this, am I to understand that increasing a machine's physical memory above 1gig is useless for Excel in the current version? My specific issue is I have a very involved worksheet that takes about 2.5 minutes to calculate and this will increase as more data is added, it is heavy formula laden. I was going to increase memory from 2gig to 4gig to assist in reducing the calculation time.

I am working on a spreadsheet that is very large. Opening the spreadsheet and even operating the spreadsheet with the cells off of manual calc can slow down the computer quite a bit.

Calculating usage...
Take the Current date and I need that inventory ---- find the date 7 days before this date ---- get the inventory for that date --- current inventory - previous inventory / 7 will give me the daily usage... the data will be in a pivot table so I need to make sure it doesnt change the usage when moving the table around...
