Unbound Combo Refresh

[golfinray]

I have an unbound combo on a form that is summing a value from a subform.
(=sum([project payments]) I need it to update as I change from one record to
the next in the main form. The mainform and subform are linked by project #.
Thanks!!!

me.unboundcombo.requery in the form current event would be my initial
thought...
