How does one get the answer to clear when user refreshes page?

[tpgames]

Here is the code for 1 question and answer, and the play again code. When I use a play again code, the answers do not erase.
What code am I missing? Thanks!

I did find a silly work around, but forcing user to navigate off page and then back to the page is a bit much.
If you need the page link, its at http://www.tpgames.net/gaming/2/exam/math/1/mycode.html
(I have issues getting links right using ff, so skiped it this time.)
Thanks again!

Just use a reset button.

Whats the difference in code between a refresh button and a reset button?
How does the reset button reset all the answers to all 20 questions?
Thanks!

A reset button is an automatic feature easily included with any form by adding the following line:
[HTML]<input type="reset" ...etc..[/HTML]
The beauty is that the effect is instant. It resets everything on the form to its state when the page loaded.

Never mind! I figured out my questions. :>) I got it to work. Thanks for your info!
