I created an Excel 2010 macro enabled workbook (.xlsm) which calculates the letter grades of test scores between 1 and 100.

To use the workbook:

1. Put the scores in one column of the open worksheet.

2. Select the first score with the mouse (i.e. make this the "active cell").

3.Click on the "Calculate Grades" button on the sheet.

Public Function LGrade(ByVal score As Variant) As String
'Returns the letter grade based on a test score.

Excel 2010 :: Ongoing Line Or Scatter Chart Don't Want Bar To Drop To Zero On Blanks

Jan 29, 2014

I'm using Excel 2010

I'm working on a workbook for tracking debt. It has 15 sheets. Instructions, Charts (for showing debt change over time), "Invisible" (this is where my chart data is, I plan to hide it), and 12 month sheets. On the Invisible sheet, for example, I have my data set up. I'm pulling the data from other sheets. In the screenshot, I'm using =Month12!P48 as the formula to pull my data from the other sheets. But, the user hasn't entered data yet for month 12, so the line chart drops to zero there. I want it to just stop and do nothing, until there is data in that cell. (I would prefer to use a line chart vs a scatter chart for this, but I have the same problem in both)

Excel 2010 :: Price Lookup Based On Width X Drop Values

Mar 14, 2012

I'm trying to create a excel sheet which will automatically return a price based on a given width and drop value. Currently, I calculate the price manually by looking in a price book which has plenty of rows and columns and prices. I want to simplify this by simply entering the dimensions so it automatically calculates price based on the dimensions entered.

Below is the start of my worksheet. If I choose the exact sizes shown on the table, it will return a price, however if I choose a size that is not listed, I get an #N/A. Eg. If I choose 780 x 1500, it will return the price $179, but if I choose for instance 775 x 1490, it only returns #N/A, when I want it to still return the price $179.

My formula in K3 is
=IF(AND($I$3>0,$J$3>0),INDEX($A$3:$F$8,MATCh(J3,$A$3:$A$8,0),MATCH(I3,$A$3:$F$3,0)))

Excel 2010 :: Populate Cells From Listbox Drag / Drop - Can't Find First Empty Row On Worksheet

Feb 1, 2014

I am running Excel 2010 and Windows 7.

I have a form with a main list box and several other list boxes. I drag and drop records from the main list box to the others. When I drop a record onto one of the list boxes, a corresponding worksheet is updated with the same record. This works just fine.

The problem I have is:I close and re-open the form after having added some dataDrag/Drop a record to the list boxThe worksheet won't find the first empty rowExample: If the worksheet already contains 4 rows of data, I have to drag/drop 5 times before the fifth row will be updatedI would like to drop the data the first time and have the first blank row updated

Notes:

1.) I have tried variations of "xlUp", "xlDown", and SpecialCells(xlCellTypeLastCell) in the "Worksheets("Monday")... line of code; all to no avail.

2.) The cells contain formatting (borders)

Here is the relevant code:

Code:

'Copy items from the list box to the worksheet
For intI = 1 To ListBox2.ListCount
For intJ = 1 To ListBox2.ColumnCount
If IsEmpty(Worksheets("Monday").Cells(intI + 1, intJ)) Then
Worksheets("Monday").Cells(intI + 1, intJ).Value = ListBox2.List(intI - 1, intJ - 1)
End If
Next intJ
Next intI

Little Calculator Wanted

Jan 10, 2007

I've been trying but excel does not seem to recognise x and y

so here it is

2* X = Z

Where 2 is changable
X = Z-2

Now i just want to find what Z is.

Here's an Example
1.3x - z
1.3(x-.06) = z
1.3z - .078 = z
1.3z = z + .78
1.3z-z = .78
.3z = .78
z = .78/.3
z = 2.6

Birthday Calculator

Jan 26, 2009

I am hopeless at remembering birthdays tbh - so rather than rely on family to remind me, I decided to make a spreadsheet that shows: D.O.B, current age (in years, months, days), and number of days remaining until next birthday.

Please see attached - I can't figure out why the current age calculation is a month out. e.g 'Sebastian' was born on 16 Nov 2008, which makes him 3 months and 11 days old - but '=TODAY()-C16' yields "00 Years 4 Month(s) 12 Days"

Also, 'Leah' has just her birthday - but now where it is supposed to give 'days until next birthday' it gives an error with the formula: '=DATEDIF(TODAY(),EDATE(C4,(YEAR(NOW())-YEAR(C4))*12),"d")'

Freight Calculator

Nov 16, 2009

I'm building a freight calculator and am considering some professional consulting options, but before I do that I wanted to see if I could overcome this one problem. If I can, I think I might be able to complete the calculator myself.

Here's my conundrum:

A potential customer enters "80802" for zip code and "Solomon" for store.

StoreLocation_________ City_______ State_____ Zip______ Distance
Solomon__________ Arapahoe _______CO ____ 80802_____ 270
Garden City_______ Arapahoe_______ CO _____80802_____ 143

The formula (or series of formulas) I'm looking for would then refer to the following hidden sheet and return Arapahoe, CO and a distance of 270 miles from Solomon.

Progress Tax Calculator

Jun 19, 2006

I'm trying to come up with an efficient formulae or function to calculate tax

The problem I have is that the tax is progressive. As below

the first 20,000 is taxed at 5%
the next 20,000 is taxed at 6%
the next 20,000 is taxed at 7%
the next 20,000 is taxed at 8%
the next 20,000 is taxed at 9%
more than 100,000 is taxed at 10%

I'm trying to do a formula like below

Cell B3 is my taxable amount
Cell B5 =IF(B$3>20000,20000*0.05,B$3*0.05)
Cell B6 =IF(B$3>40000,40000*0.05,(B$3-20000)*0.05)

This gives me a problem in that for 35k say, I end up with a negative number for the second part in cell B6. My other issue is that each calculation will take up 6 rows on my
spreadsheet. I was hoping to set up a function that could do this in a cell, but even the simple stage defeats me at the moment.

The numbers are skewed, as though the layout is in landscape view instead of portrate. I've tried repeately to delete it from the toolbars menu option, with no success. It's become annoying.

Absence Calculator

Jan 30, 2008

im trying to put together a system on worksheets that checks 'Absence' in a rolling 12 month period. The 12 month period is any 12 months and not a financial period (eg 25/12/06 -25/12/07).

I have 36 employees and want to have their names in each sheet, calander dates across the top, will mark either a 'S' for sick or 'L' for late ect against the dates if not at work.

Once an absence has been entered, on the sheet somewhere it will show how many days that person has been off (eg, 10th Oct, 16 Nov and 22 Dec would = 3 Days absence).

How do I set up the sheets to work out how many days each person has had off in a rolling 12 month period (so that it does not calculate beyond the 12 months).

I have looked on here to see if there are any programs, formulas which may work but some have lost me in my tracks.

Age Based Calculator

So in I have the following data in columns starting at B4 and ending at k4:

Date of birth; start date; text; text; text; text; Weekly Pay; Start age; Current Age; Years Service.

The formula I need to provide in l4, m4 and n4 comes from the following rules:

* 0.5 week's pay for each full year of service where age during year less than 22
* 1.0 week's pay for each full year of service where age during year is 22 or above, but less than 41
* 1.5 weeks' pay for each full year of service where age during year is 41+

So in l4 I have:

Billing Calculator

Aug 12, 2008

I'm working on a 4-week billing calculator. I rent equipment on a day,week & month rate system. For example: Equipment 1 rents at $30 Day, $90 Week, & $270 a month. If you keep Equipment 1 for 4 days the calculator computes 4 days at a total of $120. The way a 4-week cycle works is the customer will receive the cheaper rate once the daily rate meets or exceeds the weekly rate.

So instead of $120 for 4 days, the calculator tells me to bill him for 1 week at $90 instead and the customer essentially will get the following 3 days at no extra charge until the cycle starts over. As the cycle continues, the same rules apply for the monthly rate in relation to the weekly rate & daily rate combined.

Once the weekly + daily rates add up to equal or more than the monthly, then the monthly rate is used and that's what the customer pays. What I'm trying to do is make a calculator that I input the rates and the rental period and the spread sheet will tell me (based on those rules) how many days, weeks and/or months the customer needs to pay and how much his total dollar amount will be.

Golf Calculator

Feb 6, 2009

Not sure if this is do-able but I figured I would try. For a golf league coming up later this year I want to figure out how many Birdies, Pars, Bogies, Dbl. Bogies and Others each (20) golfers have during the season. After each round I would input their scores and I am looking for a program that would look at the score of the hole and the par for the hole and figure out what they got 1 under par = birdie, even par = par, 1 over = bogie, 2 over = dbl bogie and 3 over = other.

I started by creating a simple if statement but it ran out too long and my other issue is adding up the number of birdies, pars..etc for each round. Meaning a golfer can have bogies on hole #1 and #2 and the if statement can take care of that but how would get a total saying the golfer had 2 bogies.

Something like this with the - meaning a column.

birdies Pars bogies dbl bogies others total holes
4 - 5 - 3 - 4 - 4 - 5 - 6 - 5 - 8 1 4 2 1 1 9

I would do this each week and total the number of each to keep a running total at the bottom of each column. We play on the same course each week so the pars for each hole can be hard coded.

Date Calculator

Oct 22, 2009

10 days from -start date- is:
15 days from -start date- is:
20 days from -start date- is:
and so on...

I need a formula to return a date that is however many days specified from the start date. If that date lands on a sat or sun I need it to return me the date for the monday after. For example, if my start date is 10/15/09 (thursday) and 10 days from that is 10/25/09 (sunday) I need it to return the date of 10/26/09 (monday). I also need it exclude a range of holidays i have listed.

Staffing Calculator

May 4, 2007

I've been trying to create a Staffing calculator for a call center. Basically the calculator should be able to add up the number of agents for the next 18 intervals based on the login time that is entered by the user. I've just outlined the functioning below:

Suppose 10 agents login at 8 AM (thus logout at 5 PM), the intervals right from 8 AM till 5 PM should show up the 10 agents. Now suppose 10 more agents login at 9 AM, we would then have 20 agents logged in till 5 PM (since agents logged in at 8 will logout at 5) & the remaining 10 till 6 PM. Thus if we have 10 more agents logging in at 10:30, we will have 30 agents till 5 PM, 20 till 6 PM & 10 agents till 7:30 PM & so on. I have attached an excel file to explain the example & the way the calculator has to be built. It is preferrable that the cells containing the login time aren't fixed, but the user should be able to input any login time in any cell.

Commission Calculator

Jan 22, 2008

Attached is sample data. Target payout is the amount of the base salary a salesman can earn if all goals are reached. Commissions are payed quarterly. Listed on the left are 7 goals, each with a weight of importance toward the target payout amount. The percentage achieved can only be 100% or 0%, nowhere in the middle, although they are allowed to make up a goal later if they do not make it at first. This is where I get stumped. For example, if they don't make a goal in quarter one but make the goal in quarter two plus what they missed in one, they get two quarters worth of commission in quarter 2 for that goal. I am having trouble figuring out the easiest way to go about this.

Populate Drop-Down Based On Another Drop-Down Choice

Oct 25, 2006

Here is what I'm trying to do:

I have 4 sheets:
1 called main
1 called states
1 called counties
1 called people

On "main" I have 1 drop down box and 1 cell:

the drop down lists the states from "states" sheet
the cell, which i would like to have as a drop down is supposed to be listing the counties in the state selected from the 1st drop down. right now it is setting the value to TRUE for testing purposes.

then when the county is selected, it will display the people in that county listed in "people". So far I can only get the 1st drop down to list the states. that's the easy part. i need to getting the counties to list in another drop down based on what state is selected.

Populate Drop-Down Based On Another Drop-Down Selection ...

Dec 5, 2007

Im a fairly basic VBA user who has just purchased the code for J-Walk's Enhanced Data Form.

On other threads in this forum I have noticed a lot of people asking how to make the contents of one drop-down box dependant on the selection in another. I am trying to do the same thing but with the criteria section of the EDF form.

Is this possible? What does give me hope is that a simple Autofilter - whilst not as aesthetically pleasing, does the job well.

Populate Drop-Down Based On Another Drop-Down Selection

Aug 7, 2008

Currently I have columns fixed or assigned to the names of insurance providers/companies.

In each column below the name of the Insurance Company, a combobox containing the plans that company offers. Choose a plan, and the rest of the column is filled in using vlookup.

Now to save space, IE opposed to having 13-15 columns one assigned to each Insurance Company/Provider. I am looking to have only 3-5 columns with a first initial combobox in which one chooses the Name of the Company/Provider, and in turn populate the original combobox and vlookup functionality I already have built in.

Here is an example of what I am working with.
