See: Editing record access privileges - you'll want to set up a FileMaker account for each user, and they can all share the same privilege set. In that set you'd limit record access where their login user name = user name field.
You'll want a script that runs on file open that searches for their record and hides and locks the status area. You'll need to provide buttons to replace the functions from the status area such as Edit, Submit, and Log out.
Can I pay you to help me with this, by using the gotomypc service which I subscribe to? I can email you my cell phone number if your interested. I can pay you by using pay pal or some other way that you are already aware of. I am not as advance as you and it seems like I am not a "quick read" type. Richard
