May want to check out the ON ERROR command. That might help.

>If i have a field-level validation or record-level validation and it fails, visual foxpro shows a window with three options: ok, revert or help.

>
>1. it's not clear to an end-user what to do when the options are Ok, Revert or help.

>2. I want to decide what to do, and show a more elegant message.

>3. My users don't speak english, so this message increases confussion.
