Yes, seen it, and it's obviously the wrong thing to do or I'd be getting the result I'm looking for. But I can't see the correct way of doing it. I.e. I can't see any way of setting each element of the list to a function with a different 'form' value without using some 'i' like variable in a loop. I don't think it's something obvious I've missed...
