How to set fields in a form to be mandatory
You don't. Controls themselves have no property to make entry a
requirement. You set the fields they are bound to as "Required = Yes" in the
table that the form is bound to.
Alternatively, you can use code in the form's BeforeUpdate event that checks
all of the controls you want to be required and displays a message if any
are not filled in. That is not as reliable as using the required field
strategy, but is more flexible.
