Hi Steve,

Its really good question. Infact my combo not having invalid valu...but I am checking another value in table on the basis of combo selection. If its found according to criteria than dislay on next form otherwise give appropriate message and cursor should be there to wait for next selection.

Hope I can explain you clearly.
Any further clarification required higly appreciated to share my thought.

Best regards,
Sajjad
