Many thanks for the time you put into coming up with a possible solution. I
will be giving it a try. I do need for the user to be able to view
historical data that has been entered. Your method should facilitate this.

An accumulator cell idea is risky idea. Mistakes are difficult to find and
correct.

Having said that, here is a method you can try.

Add this event code to the sheet with the entry cell at A1

Add a new sheet named Retriever

You can hide that sheet if you wish. It is just used to collect the entries
made in A1

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
'accumulator/summer
On Error GoTo stoppit
Application.EnableEvents = False
If Target.Address = "$A$1" And Target.Value < "" Then
Sheets("Retriever").Cells(Rows.Count, "A").End(xlUp) _
.Offset(1, 0).Value = Target.Value
End If
stoppit:
Application.EnableEvents = True
End Sub

In whatever cell on the "separate worksheet" you want the accumulated value
enter =SUM(Retriever!A2:A1000)

If user makes a mistake you at least have a list of all entries to peruse.

Note: to correct a mistake, you will have enter a negative number to
subtract the mistake from the SUM formula.

I want to allow the user to type an Integer value into a worksheet cell. The
cell value is added to the previous cell entries from that same cell and
displayed in a linked cell on a separate worksheet.

If possible, all values for previous weeks entries on the worksheet can be
retrieved and displayed without the need to store each spreadsheet as a
separate file.

Any help on this would be grealty appreciated
