Hi, I would like to create a mailing list where there are no duplicates. It should check while the user is entering data if any previous records exist with the same data. For example, if there is a John Smith residing at 123 Oldsville Road, Somewhere, SM with phone number 12345, as soon as the user enters John in the 'First Name' Access should pop up all records matching first name John. When the user enters Smith, all records with John Smith should show up. Same record searching for phone number, address fields etc. The user does not need to necessarily enter data in a certain order. If he enters only the phone number, it should show up all records with that phone number. I hope I haven't left any confusion. Thanks, Zef.
