Hello Kennedy,
thanks for the response.
the script you had given will only block to add draft if my UDF "U_HEQUIPT" is null, but it does not evaluate if the given value in UDF "U_HEQUIPT" is valid based on "@HEQUIPT" UDT.... that is my problem, i can only trap if the field is empty or null but i cannot trap if the user had entered a valid value in the field....
please help with my requirement, every input is highly appreciated.
thank you..
Fidel
