Akilah,
Well, usually Amount_Due is a calculated field (ex.=Price * Qty), but if
Amount_Due is entered manually, you would use the AfterUpdate event of
Amount_Due to...
Private Sub Amount_Due AfterUpdate()
Me.Current_Value = ' your calculation here...
End Sub
Or, create a Macro using SetValue to calculate Current_Value
But, if... given any Amount_Due value, if you can always recalculate
Current_Value (on the fly), then you shouldn't be storing Current_Value at
all.
