ive duplicated a simple questionnaire as shown here:
http://www.hackeradio.com/questionnaire.html
meaning there are 8 questions, each with 8 possible answers.
Each row of the answers has its own name ie:
question12_answer1 - question12_answer8
and each of those has a value of 1 - 8
[...]
on form submit i want to run a bit of code(already got this set up) so
that I can validate if only one answer 1 has been selected, one answer 2
and so on.
So 1 can only be used once, 2 can be used only once, all the way to 8.
