Do you mean when they Edit the record? Look at TableUpdate(). If the second parameter is .T., it will overwrite the record without warning. Change this parameter to .F., TableUpdate() will then return .F., indicating that it can't update the record because someone else changed it since it was buffered. You can then use CURVAL() and OLDVAL(), the current value (just the value of the field, and GETFLDSTATE() to determine what has changed.

If your problem comes when two people append a new record, you have a bug in your primary key generation.
