I have Excel 2007, so I go to the developer tab, then click on Macros and choose the macro to run and click run. When I create a new one I click on record macro. The document has three macros right now. One that creates a unique quote # every time the document is opened and then the two you gave me.
Macro 1:
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
With Worksheets("Sheet1").Range("G3")
.Value = .Value + 1
End With
End Sub
