Instant Totals on Continuous Forms

[Ira]

I have a continuous form with each record containing 3 fields:
ORDERED, RECVD and a CHECKBOX named CLOSED. In the footer of the form
I have 2 fields that calculate totals for ORDERED AND RECVD using
SUM(). I am trying to get those totals to update instantly without
have to jump off the current record or REQUERY the whole form. When I
click the checkbox, it fills the RECVD field with the same number
that
was in the ORDERED field. I want to "close" the order and lock the
form when the total ORDERED equals the total RECVD. But when I am on
on the last record of the continous form I have to move off the
record
to get the totals to update. Is there a way to get the totals to
update while I am still on that current record (the focus is still on
the checkbox that I just checked)?

Thanks
