Is the date displaying the way you want it to in the table but not the form, or is it not displaying properly in either?
To change the date format in the table go to the table design view and change the format of the field to dd\.mm\.yy
To change the date format in the form go to the control that you wish to change and select the properties to to the format field and enter dd\.mm\.yy
hope that helps,
