Answer 1

Hi,
create a validation of type "Function returning a Boolean" and put something like
DECLARE
   TEST date;
BEGIN
   TEST := TO_DATE(:YOUR_ITEM, 'DD-MON-YYYY');
   RETURN TRUE;
EXCEPTION WHEN OTHERS
THEN RETURN FALSE;
END;to the Validation Expression 1.
Enter your message to the "Error message" box and that should be it.
Hope this helps...
Thanks
Sandro
