Will Although typically radio buttons always start with the first option selected (unless another is manually SELECTED), it's possible that NONE will be selected, especially if the form page were reloaded (doubly especially in FF), so you're right, you need a fallback.
The typical fallback strategy is <cfparam>, but that assumes a default value, and a db INSERT always. What would you like happen if none is selected? That's the real question. (For some reason I want to say "do you feel lucky punk", but that may not be appropriate here). Mik At 09:19 PM 3/15/2007, you wrote: >I have a form with dynamically created radio buttons.
