Excel 2003, Sp2

Hi

I want to track changes in cells made by the user in the workbook. I use the
Workbook_SheetChange event.
The example below prints the value the user changed TO. Howerver, sometimes
I want to print the value the user changed FROM.

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Debug.Print Target.Value
End Sub

How can I find out the value the user changed FROM?

Regards
Pete
