>Cetin, I did waht you suggested , but with no luck.
>I then moved code to the Valid of MyStkGrp which DID work e.g.
> This.Parent.cboStock,Rowsource = 'Select * from.......'

>My other combo that works: Select * from MyFile Where Myfield = 'XXX'

>The only differencr I can see from the two combos is :
>
>On the combo that did not work, the select field was depending on data entered on the form (i.e. MyStkGrp.Value)
>
>On the Combo that was ok, there was no dependance
>.i.e It was selecting based on a value ('XXX')
>
>I also set up another form from scratch just to test out and I was able to replicate the problem.

>Woild you have any idea why there is different behaviour for the two combos ?
