I have a form with a subform which has the Default View set to Continuous
Form. In the subform header is a textbox which contains a value used for a
calculation in each record in the subform. If the value in the textbox in
the header is changed, I want all of the records in the subform to be
re-calculated. The problem I'm having is that only the current record is
being re-calculated. How can I have all the records re-calculate instead of
just the current one?
