On exit of subform

[Robert Nusz @ DPS]

I have a tabbed form which allows entry of primary records of keyed table
(there are four tabs total, three tabs contain fields of data for primary
record, fourth tab holds subform for secondary records.) This subform allows
entry of secondary table records pertaining to primary table, (example of
supplier / products table). Secondary table is related to primary table via
keyed /foreign key account numbers with master / child link on these numbers.


What function occurs when the user leaves a subform and returns to the
primary form? I need to know what happens when a user leaves the subform to
return to create another primary record, as there are unbound fields on both
primary form and subform that hold data that may or may not be pertinent to
the next record entered by user. How do I clear my unbound fields and at
what function/switch?

Is this return from subform to other tabbed panels of the primary form a
"lost focus", a "Deactivate", a "unload" of the subform or what? I'm too new
to Access to fully understand what happens on tabbed for changes?

thanks,
