Define an input mask for a field in a table

1. Open a table in Design view.
   
   
2. In the upper portion of the window, click the field you want to define an input mask for.
   
   
3. In the lower portion of the window on the General tab, click the Build button next to the InputMask property box to start the Input Mask wizard, and then follow the instructions in the wizard dialog boxes.

Note   You can also enter the input mask definition in the property sheet without using the wizard. In most cases, it's easiest to use the wizard, but for Number and Currency fields, you must enter the input mask definition manually. For information on how to define an input mask manually, click .
