The Expression Builder box helps you build expressions more quickly and accurately with smart tools and context-sensitive information. The following video shows how to use the Expression Builder to create a common expression for a calculated field. Tip If you see the word expression in a menu, you can click it to start the Expression Builder. In this articleĪlthough the Expression Builder is available from many locations in Access, the most consistent way to display it is to put focus on a property box that takes an expression, such as Control Source or Default Value, and then click Expression Builder or press CTRL+F2.
