Formula for balance forward

[narrowgate88]

I'm attaching a file that has a tab for Jan and a tab for Feb. I want to create a formula on Feb's B3 to auto pull the ending balance from the Jan tab. Then as I add a new tab each month, I want it to always pull the info from the prior month's tab. The ending balance may or may not always be in the same cell.

If you are going to place the current month information in A1 for each new sheet, so that we can use that to reference previous months' sheet, then change the entry in A1 to a true date, like Feb 1, 2010 and format as mmm yyyy.

Then assuming you want the last number entered in column B... try:

=LOOKUP(9.999999E+307,INDIRECT("'"&TEXT(EOMONTH($A$1,-1),"mmmyyyy")&"'!B:B"))

While I was waiting, I found a UDF that works pretty well.

Function PrevSheet(rg As Range)
n = Application.Caller.Parent.Index
If n = 1 Then
PrevSheet = CVErr(xlErrRef)
ElseIf TypeName(Sheets(n - 1)) = "Chart" Then
PrevSheet = CVErr(xlErrNA)
Else
PrevSheet = Sheets(n - 1).Range(rg.Address).Value
End If
End Function

And then on the spreadsheet, I'm using this formula.

=(PrevSheet(B5))

I have since discovered that B5 is not always the right cell since there may be more data some months. So I really need to incorporate some kind of EndUp type of statement so that instead of B5, I'm referencing the last cell in the column with data. How can I do that?

You can use the method described here to get the previous sheet name:

and then use formula:

=Lookup(9.99999e+307,INDIRECT("'"&PrevSheet&"'!B:B"))

oops. the forum screws up the link... if you google this exact phrase: Referring to Previous Sheet then pick the first link to Daily Dose of Excel, you will get to the same page.

I cannot get the website to open.

I added more information above....

Could you stick the lookup formula in code brackets.

You mean?

=Lookup(9.99999e+307,INDIRECT("'"&PrevSheet&"'!B:B"))
