The solution I recommended is using a cursor and the building of the list for the second combo is IN the seocnd combo and not some other object.


Jim;
Thankyou for your reply. I resolved the issue by trying "one" more thing!!!!
I defined the array as Public in the form's init, which works fine. But I found out that if the array size changes programitcally, the Combo Box 'NumberOfElement' doesn't update, and I must issue a ThisForm.cboMyCombo.NumberOfElemets = ALEN(aMyArray)
