form element values

[gr3gg0r]

if i have a form that has two input text boxes, how do i get it so i can have a value be input to the first box, then when i click submit, a calculation is done, and the out put is displayed in the second box?

How would i get it to do it in real time? (ie, without having to press submit, the output would update with every change in the input box.)

this cannot be done with PHP, you must use client-side code (javascript).

ok, thanks, i didn't think it was possible, but i wasn't sure. How about my first question though??
