I have this code working in an .xls file but it won't work in another whether it is .xls or .xlsm
I have another formula in conditional formatting working with this macro to highlight the row/column of the active cell.
I can do an F9 recalculate to make the formatting work, can't figure out how to make it auto calculate
like it does in the other spreadsheet.

Also, what is the signifance of the General vs. workbook and worksheet_selectionchange vs. (declarations) and open

Thanks,

Private Sub Workbook_Open()

End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Application.ScreenUpdating = True
End Sub
