Access Validation Rule

I'm trying to set up a rule in an Access database that will check if a number has been entered in a previous record and if it has reject it.

I've set the number as the primary key and selected Indexed (yes no duplicates)but it's still allowing duplicates to be entered.

I'd be grateful for any suggestions you may have

Jim
