I have the following macro that works great upon exiting my workbook but how
can I modify it to prevent calculations from running whenever someone opens
it? There are so many formulas and so much data on each sheet that if we
don't calculate each sheet manually, then we have to end task on Excel
because it will not complete the calculations.

Thanks!

Randy

Private Sub Workbook_Open()

With Application
.Calculation = xlManual
.CalculateBeforeSave = False
End With

End Sub
