Passing variables from javascript to php

I decided to try and learn some javascript. Being the pure simpleton that I am, I tested the oh-so-simple: <script language="JavaScript"> <!-- abc=window.prompt("Please enter a word."); // --> </script> I know it stores the variable because document.write(abc) prints it but the variable apparently doesn't pass to php... <? echo("$abc");?> //placed after the </script> tag soooooo, what should I be aware of in order to make it work? thank you __________________________________________________ Do You Yahoo!?
