Access Problem

Here’s the scenario. I have created a Salesman Database where our Salesman can open the Database with no permissions except to open their own table and update their customer information. Example, Alan can login and only open the Alan table. All other tables cannot even be viewed. What I really would like would be a form that started up. Then Alan would be shown his table and he could start editing his information. So basically I would like a form that would open up and depending on the login bring up the appropriate table. Can anyone help here?
