sub form updating

[Guest]

I have a form which has two sub forms contained within it.

First sub form (lets call it sub_a) is used for some data entry, the second
(sub_b) displays some information as a result of entering data into one of
the fields in the first subform (sub_a).

How do i (after entering a result for a field in sub_a updte the contents of
sub form sub_b. I have tried all soughts of combinations of requery,
refresh, recalc within the subform sub_b, and nothing seems to quite do it
