I have an existing database imported from MS Access that is functioning with no problem. I want anyone to be able to view, but registered users can modify only their own record. All I was given with this db that was unique was a "member number" that is already assigned so I've used that as "user id" and the last name as a password and converted into .pass with no problem.

The problem is, although I can login using this combination fine, when I click modify I get 'no matching record'. After hours combing this forum and FAQ's etc I'm assuming the problem is in the db_key or auth_user_field area, I just totally can't figure it out.

Can someone point me to anywhere that explains this in detail or offer any advice?
