I want to have a rolling total on 1 cell...such as an invoice number, each
time I open a worksheet. Is there a way to do this?

I think I'd do this with a Workbook_Open event.

Copy this to the "ThisWorkbook" code module and modify as necessary.

Private Sub Workbook_Open()
On Error Resume Next
Set myws = Nothing
Set myws = Worksheets("Sheet1") 'Modify
'Alternatively
Set myws = Sheet1 'Uses worksheet codename instead
On Error GoTo 0
If Not myws Is Nothing Then
myws.Range("A1").Value = myws.Range("A1").Value + 1 '<~~~modify
End If


End Sub
