Hello all, from a Bound Form i'm looking for a simple way to prevent a user from entering a customer phone number into a table if that phone number already exists. Basically, if the phone number already exists in the table, I would like to 1) prevent that entry from occuring and 2) get a msg to pop up that reads 'Phone Number Already Exists'. Is there a Table Property or Form Property that I can set to achieve this? Thanks K
