1 | A subform is a collection of fields you plan to use more than one form. For example, you might create a corporate letterhead in a subform and then use the subform on a variety of business forms. |
2 | To control the display of a computed subform, use a formula. For example, you might offer users a choice of custom mail forms with different graphics and styles for various types of mail messages, such as memos, alerts or letters. |
