Hi, I have a form where users are to rate six different fields in order of importance, 1 being most important 6 the least. e.g. Cost 1-6, Relationshop with Supplier 1-6 etc.

I'm not sure of the best approach, I have the six fields each set as drop downs containing values 1;2;3;4;5;6 - the problem is making sure the user can only select each value once across the six fields.

I'd normally just write a bit of javascript to attach to each drop down's onChange to check the others, I'm not very familiar with DNN's form and list, any help would be greatly appreciated.
