Access Event Tutorial - AfterUpdate VBA:
In this AfterUpdate event example we requery a grand total field on the master
form after records are updated in the detail form:
Private Sub Form_AfterUpdate()
Note: When validating form field values it is important to know that the

event for the form occurs.
If you decide to cancel the update the value of the OldValue property
replaces the changed value in the control.
