ERROR: The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.
I have a service tracking DB which is divided into 2 sections customer data which is pulled from linked SQL tables and is not editable and repair data which the user enters. I am getting the above error when more than one user is entering data into the Repair Information section which consists of 2 sub forms, I have changed the Record Locks property to Edited Record on all forms but still get the error, and I have also repaired and compacted the DB. The error does not appear if only one user is entering data. Any suggestions would be greatly appreciated. I have included a screen shot of the form.
