Radio buttons on forms

[Paula Edmiston]

I just discovered that it's not possible to have an unselected radio
button. I'm working with a free perl script to process a form. The script
checks to see if any question was unanswered and if so, following the
submission, it directs the user to return to the form and answer that
question.

How to make sure every question is answered? Due to the nature of the
survey I can't substitute check boxes or text input. I need those radio
buttons.

Perhaps always an option "UNanswered" so that when processing the form a
query can be applied that is the value is UNanswered, return to answer
that question. (I don't know perl so I can't really adapt the script to
say "if the value is "UNanswered" return to complete the form). I think I
could try it in php, I am just now learning that language (has anyone done
this that would be willing to help me?).

Has anyone here run up against that problem without coding around it in a
language like php or perl? I would rather NOT use javascript as I don't
want to be dependent on the user having js turned on.

Any assistance or comments will be greatly appreciated.

best,
paula
