subform x set up the source table x
added a combo from some other table linked(table y)
when I modify the combo
I want as a aftermodify event to update a field on subform x
whats the easiest way?
Lookup, as Rich said albeit minimally, the domain aggregate functions such as DLookup, DSum, DAvg, DCount, etc. which can get actual values from a recordset.
You don't need the combo in the table, only the form, change the table display to a text box.Requery the subform control on the AfterUpdate event of the first combo
