[thelist] request JS help for quiz

[Sharon F. Malone]

Hi Kristol -

When I tried re-writing it (because each question is wrapped in <.form><./form> tags!!!!!!), it totally bombed. Since my JS knowledge is not so hot, I worked around the original code and got it to work.

Thanks for the quiz code you provided. I'll work with it the next time.

Best,
Sharon
