I found this response in another similar inquiry --- this resolved my problem:

==========================================
If you're willing to use a User Defined Function.......


Function PrevSheet(rg As Range)
'Enter =PrevSheet(B1) on sheet2 and you'll get B1 from sheet1.
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

Say you have 12 sheets, sheet1 through sheet12.

Select sheet2 and SHIFT + Click sheet12

In B1 enter =PrevSheet(A1)

Ungroup the sheets.

Each B1 will have the contents of the previous sheet's A1

Copy/paste the UDF above into a General Module in your workbook.

If not familiar with macros and VBA, visit David McRitchie's website on
"getting started".

In the meantime..........

To create a General Module, hit ALT + F11 to open the Visual Basic Editor.

Hit CRTL + R to open Project Explorer.

Find your workbook/project and select it.

Right-click and InsertModule. Paste the above code in there. Save the
workbook and hit ALT + Q to return to your workbook.

How do I reference the worksheet immediately preceeding the current
worksheet? I would then like to copy that formula onto the next worksheet,
so that it automatically adjusts to reference the current worksheet (which is
its preceeding worksheet).
