The Simplest of Lookup Lists - the Y/N Drop Down List
First you may say why use a Y/N field - use a check box.
The answer is: don't use check boxes on forms! They are difficult to sort by and simply clicking in or near the field will cause the value to change - often accidentally.
Use a text field in your table with a length of 1. Put a Validation Rule such as: 'in ("Y","N")'. Don't define a lookup in the table design (while not as important on a Y/N field, you'll see why this is discourage in discussions in our other examples).
In form design view click the icon for a Combo Box and drop it in your form. The combo box wizard will activate. Choose to enter your own values. Then put a Y in the first line and a N in the second line. In may choose a default answer in the next screen. Finally, tell the wizard with which table field the
combo box will be associated.
