Hi,

I have a form with two controls. If a user has entered something in control 1 I want to be sure something has been entered in control 2. The opposite also applies i.e. if something is in 2, something must also be in 1. Both these controls can be empty though and i don't actually care what is entered format or datatype. One control is a dropdown list, the other is a textbox.

How do I do this? I've played with the validation controls but no luck so far.

Thanks,
Andrew
