I have about 18 radio buttons, each bound to their own field. They are all in the same section. However, a user is able to select more then one of these buttons. I want the user to only be able to select one of these buttons. I know this can be done if they are bound to the same element, but is there a way to do it if they are bound to separate elements?

Hi, I tried this in a simple form - please see attached. I think that's what you're looking for. Please feel free to contact us if you need further help on your form. :) Cheers!

Thank you! Yes that is what I was looking for. I ended up turning my radio buttons into a drop down list though to meet deadlines :) I also later discovered this can be done via code behind and xml changed events but with 20+ radio buttons that would take forever to write out.
