Sorry, forgot to reply to your earlier suggestion Jason. Agree that it is no 
really necessary, but it can be difficult to convince people of that…

As for the compulsory pair, I though that would only ensure that there is some 
value in both fields - but what I need is to ensure that if A is «no», the B 
SHOULD be empty - and if a is «yes», it should NOT be empty. Can I do that with 
a compulsory pair?
