THANK YOU ALL FOR YOUR HELP!!

I didn´t know that SEEK would try to update the table so that was the whole thing.

I'll use a second copy of my table since I have to let the user enter the number, and not automatically assign one, I just want to avoid those FUNNY users that repeat the same ID number just to see what happens Even if it´s the Telephone number wich should be unique on every single person or company.

Again thank you for your time !
