Data required IF statement

[CraigBFG]

Is there a way that I can say...

If Course_Expires? = Yes then Course_Expiry=IsRequired.

I've managed to get the DateExpiry field to enable/disable based on the Expires question?

If Me!Course_Expires.Value = True Then
Me!Course_Expiry.Enabled = True

Use the current event to do this.

As you haven't used any prefixes, I can only guess that CourseExpires is a checkbox. If so, use True rather than Yes.
