I have created a simple create_user form and have a question about form validatioin.  Currently the guest name and terms are the only feilds that are required.  However I would like to make the form error out if either phone number or email address are not provided.  Making these required fields is not an option for my customer. 

 

 

Feilds present are: Guest Name, Phone Number, Email and Terms and Conditions.

 

 

 

 

 When you edit the form the "Field Must Be Supplied" attribute must be checked:

 

That option is selected for both the guest_name and terms and conditions feild. What I would like to happen is in the guest_name form have validation set to check to see if either the phone number or email address feild are filed out, if not return a validation error "please enter either phone number or email address".

That would be the "Validation Error" parameter:
