MS Access Version 2007 running on XP-SP3. I have created a Form and on the Form I have added a Tab Control with two pages. On the first page I have added fields from one table and on the second page I have added fields from another table. These tables have a relationship on a common field. In Design View all fields are visible. When I select Form View the form goes blank. I have saved the form and and re-opened it but it still does not display. The Form will display if I only use fields from a single table. The critical point I notice is adding a field from another table. I would be very grateful if anyone has any suggestions on how I can get round this issue. Thanks Karl
