Copy/paste this UDF to a general module in your workbook.

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

Example of usage...................

Say you have 12 sheets, sheet1 through sheet12...........sheet names don't
matter.

In sheet1 you have a formula in A10 =SUM(A1:A9)

Select second sheet and SHIFT + Click last sheet

In active sheet A10 enter =SUM(PrevSheet(A10),A1:A9)

Ungroup the sheets.

Each A10 will have the sum of the previous sheet's A10 plus the sum of the
current sheet's A1:A9

How do I export one cell's data to another sheet within the same workbook?
For example, I'm making a budget for the whole year, so I want the ending
balance from January to automatically show up in February and so on. (January
is in one sheet, February on another, and so on)
