I tried to SET NOTIFY OFF but the "Invalid Date (press space)" message still appears ! Could there be another reason ?

>>How can I use my own error message when an invalid date is entered in a date field ? The system shows this message i.e. "Invalid Date (press space)" at the bottom of the screen. How do I get rid of this and show my own message ?
>All countries not using English have the same problem but this one could be overcomed like this :

>* Write your own or just return 0
>Error : "Hey you enter a correct date or leave it empty"
