I have a formula that is correct all the way up to adding the last *K9. here is an
example:
C9 a number 4 then add 1 to it which makes it 2 now * it by D9 which is the number 384 and the answer is 768 now * that by K9 which is 6 and you get 4608 I'm getting 2310 using this formula... =IF( C9=0, 0, C9+1*D9)*K9.

I have a workbook with calculations for a sale less the assorted fees and at the end giving the final amount from a sale.
I have noticed that some of the rows are not giving the correct amount in them.
In other words the addition of some columns in that row are not adding up correctly. It is only off by 1 cent (either over or under), but I can't figure out why.
I have the feeling that I am going to want to kick myself when someone explains this to me (I just know that I know the answer but for the life of me I can't right now).

Consider this code:
'light eligibility
Dim facb As String
Dim sunset As Variant
[color=green]' check if facility has lights[color]
facb = WorksheetFunction.VLookup(RID, ds, 10, False) 'find facility code
If WorksheetFunction.VLookup(facb, fac, 6, False) = "Y" Then 'facility has lights
sunset = WorksheetFunction.VLookup(tempws.Range("A9"), sun, 2, False) 'lookup the sunset time based on the record's date
[Code] ......
This code checks the need for lights at a facility.
It first checks to see if the facility even has lights by cross-referencing a value in the record with a facilities database.
If it has lights, it then checks to see if they are needed. If the rental goes past the sunset time, then it needs lights. Sunset is determined by cross-referencing the date value in sheet1! A9, with the sunset database.
If it needs lights, variable lghtson is calculated equal to "sunset"-30 minutes.
As I step through this code:
WorksheetFunction.VLookup(facb, fac, 6, False) = "Y" Facility has lights.
Check to see if lights are needed.
sunset = WorksheetFunction.VLookup(tempws.Range("A9"), sun, 2, False)
sunset=0.879166666666667 which is 9:06PM. This is a proper value from the lookup.
If rental_end.value > sunset Then
rental_end (value from textbox) = "9:30 pm" , sunset=0.879166666666667. This is true, and Excel accepts it as true ...
lghtson = sunset - 0.5
0.379166666666667 = 0.879166666666667 - 0.5 (9:06 AM)
This is not the value I was looking for. I was looking for 8:34PM (0.856944444444444)

I have two sets of two columns which contain numbers as text with trailing spaces and I want to concatenate column A and B and concatenate column F and G, and then compare them, and sumif value in column I if they are the same - giving the answer in the same row as the matching data in column A and B.. but in column J.
I’ve seen sum product and haven’t been able to get it to work at all. I have been adding the trim() function in around the column references to see if that would work but am failing…
A = 2000 text
B = 1234 text
F = 2000 trailing spaces, text
G = 1234 trailing spaces, text
I = 10,000
Answer in column J
I want 20001234 = 20001234 = 10,000 for the whole column.
I don't want to change the original data as its externally sourced and used for other links etc.. This would save a few hours a week if i ( more correctly, you ) could get this to work.

This is so simple, yet Excel doesn't give the correct value. So, here you go, I only have 2 Cells and 2 Labels. One Label for one Number and the other Label for the other Number.
For the Pie Chart I chose Cells:
Cell B36 with the number $54288
Cell B39 with the number $166113
By simply viewing this one can see one of the Percentages should be around 33% and the other 66%. However, Excel gives it a Percentage of 25% and 75%.
How can I get the correct values?

What calculation would I enter in a results cell if I wanted to find the delta between 2 times in date format that repersent just the business hours of 8am-5pm, therefore excluding after hours and weekends.
eg.
Date 1 Date 2 Result Time
23/07/07 8:00 24/07/07 14:55 15:55
So far I can't get the caluclation that will compensate for the after hours and week ends.

How to create a formula to determine the longer period of time between two date calculations and enter the longer period of time in the cell.
My Spreadsheet:
Cell M2: Birthdate (entered in cell as 11/1/2004)
Cell J2: Last date of service (entered in cell as 10/31/2011)
Cell G2: Calculation to enter the longer period of time between (M2 (year) + 21) and (J2 (year) + 7)
Example using information from above:
2004 + 21 = 2025
2011 + 7 = 2018
2025 is the result I want added to G2
If there is any way to include the month/year in G2 that would be ideal.

I'm new to VBA so my i'm having alot of problems figuring out simple stuff.
Below is my script and when i run it, the dates turns out incorrect.
I noticed this only happens to dates that are before 13th of each month.
Example,
1st May 2008 ( 01/05/2008)
will turn up as
5th Jan 2008 ( 05/01/2008)
However when i manually open the file Todays trades.csv
The date looks just fine.
Is there some problem with using VBA to call up the file?

I maintain a class register in Excel to monitor student attendance. The first row shows the date of the class in the form dd-mm.
I need to identify all dates which fall on a Monday and thought that if I custom formatted a new row as "dddd" and enter the formula =DAY(cell ref) into the cells of this new row it would achieve this- I could easily spot the Mondays for the period under review.
What I'm finding, however, is that the formula seems to incorrectly state that 16th September 2008 is a Monday whereas it's actually a Tuesday- utterly bizarre!
I can get a fix simply by modifying the =DAY() formula by adding 1 to my formula [ie =DAY(A1)+1] but am wondering is this a "so called known issue" with Excel or has anyone else come across it? I have never previously come across this and consider myself to be an above average competency level user of the application.

I would like some help from someone on this subject if possible. I am running a stats report in a workbook where each member of staff have their own running totals of how much work they do and how much of that work is incorrect (per week). I have worked out that if I use the following:-
=SUMPRODUCT(('Barry Brooks'!$A$1:$A$2000>=$B$95)*('Barry Brooks'!$A$1:$A$2000<=$C$95))
I get the total amount of work. To explain the above, it returns the amount of times a date appears between two dates i.e B95 is week commencing date and C95 is weekending; therefore giving the total amount of work in that period.
What I am struggling with is that I need a formula to look at the above date range and then look at another column that has either a ‘Y’ or ‘N’ (for yes or no) and for the formula to count how many N’s there are (thus how many in that given range there were)
It appears to me quite a small ask for Excel but I can’t seem to get it to work.

I am using VBA to export an access query into excel, the query works fine in access but when importing the data into an excel spreadsheet, it doesn't display the date column headers in the correct format.
The problem I have is that the dates 1 to 12 are displayed the wrong way round eg:
In Access date column headers from query are:
09/01/2008, 11/01/2008, 12/01/2008, 14/01/2008, 15/01/2008 etc.
But when exporting to excel, the above dates are shown as:
01/09/2008, 01/11/2008, 01/12/2008, 14/01/2008, 15/01/2008 etc
It seems to be changing round the dd/mm when I export, but only upto 12 when the day is 13 or more it is displayed correctly.

.txtDate.Value = Application.WorksheetFunction.VLookup(txtStudentName.Value, Sheets("SPANISH").Range("A2:F113"), 5, 0)
.txtTime.Value = Application.WorksheetFunction.VLookup(txtStudentName.Value, Sheets("SPANISH").Range("A2:F113"), 4, 0)
End With
End Sub
The txtTranslator and txtTime works correctly, however txtDate give me a number '40850' not a Date?
How can I change this number for the actual Date?

I am attempting to pick up a date with time entry on a worksheet and place it into a TextBox on a UserForm. Format on the sheet is mm/dd/yyyy h:mm AM/PM. The UserForm is placing the value as mm/dd/yyyy 12:00 AM. here is the
Private Sub UserForm_Initialize()
If Not Range("dDate").Value = "" Then
TextBox2.Value = Range("dDate").Value
TextBox2.Text = Format(DateValue(TextBox2.Text), "mm/dd/yy h:mm AM/PM")
Else
TextBox2.Value = ""
TextBox2.SetFocus
End If
End Sub
"dDate" is the named range where the date is sitting. The format is also set on the TextBox2 exit event. Can anyone see why only the date portion is being transfered with the default 12:00 AM for no time component of the value?

I have been burning brain cells trying to figure this out.
I get these numbers from an online source and they come in like this:
A B C D E
1/1/0912:01AM02:40AM11:18AM07:55PM
The times do not come in as times...when I format the cell to time it doesnt change...that is my first problem.
What I would need to do to these times is: take B and C and find what time is in the middle of them and put that in a different column.
This mess will also need to be plotted on a chart with time by the minute for one day as the X axis. In my example I drew lines on the chart to show what I mean....the blue lines I dont want charted...I use those to find the time in the middle.

I am trying to get a total column that will give the total only when two particular devices are down at the same time. This total will be taken from a long list of downtime entries for different devices but I only want the total when two particular devices are down, for example
Devicedatedowntimedateuptimetotal time
102/01/0911:00:0002/01/0911:09:0000:09:00
202/01/0911:00:0002/01/0911:04:0000:04:00

204/01/0913:09:0004/01/0913:12:0000:03:00
104/01/0913:02:0004/01/0913:15:0000:13:00
505/02/0905/02/09
total 1/200:07:00
In the example I am just wanting to work out the total time when both device 1 and 2 were down at the same time, above the total would be 7 minutes because for 4 minutes on the 2/1/9 and 3 minutes on the 4/1/9 they were down at the same time.

Having been looking round this site for quite some time now and always finding what I needed I am now a registered member who needs your expertise.
I have a spreadsheet for which I need to calculate hours worked depending on a few criteria.
[data] ...
The criteria is that Sat/Eve is 8pm to 6am weekdays and midnight to midnight on a saturday. Sun is midnight to midnight on a sunday, BH is a bank holiday and basic is everthing else. What I want to know is it these columns can be populated automatically using formulas.
I would really appreciate it if someone out there is up to completing this challange, as I have to manually populate this at the moment and it can be 5000+ lines long (it takes hours). If i need to change the layout it's not a problem, whatever it takes to automate it has got to be worth the effort.

I have a time card sheet that I want to make automatically calculate the time I have worked. It is set up with four columns that can't be changed. The first column is "Time In(TI)", second column "Time Out(TO)", Third column "Time Taken For Lunch(TTFL)", and Finally "Hours Worked". I have no problem getting the formula to calculate the difference in "Time In" and "Time Out" but taking the 30 minutes out of that is causing a rift. If I put the 30 minutes in 00:30:00 format it will take it but it thinks it's 12:30:00 and it displays in 00:30:00 which I want it to display 30. Just to clarify, I am using =(TI-TO)-TTFL in the Hours Worked cell.

I have loaded a .csv file in which the first column contains date/times, e.g. 01/12/2012 00:00. How do I now tell Excel (2010) that this is in fact a date/time format? If I select one or more of the cells, click on the Number dialog box launcher and try to pick a suitable format tghe cells resolutely refuse to budge from being text (i.e. left-justified, still allows me to edit the 'seconds' component to a number > 60). Also which data type should I be using? The only one that appears to have a full date/time format listed is Custom (not Date or Time).

I keep getting extra memory with no visible improvement on the processing time. Is there a trick out there that I can use? Something is clearly wrong.

I have a calculation whereby I use two variables which are 1. Man hours left in the week formatted as [hh] and 2. Amount of work left to do in the week formatted as 0" Man Hrs" I need to carry out a calc which says:- Man hours left in the week - Amount of work left to do in the week.
The answer should tell me if I have a deficit or surplus of hours which can then use for planning purposes. Unfortunately the problem I have is that I can't make the formatting the same for both unless someone knows of a workaround.
Man hours left in the week = 128. Man hours required to complete all work this week = 224. Therefore I need to say 128-224 = -96. However when I do this this an answer of 16 is returned.
