it works perfectly at stack overflow.

weebly doesn't support php.

so i have no choice but javascript.

The closing tag of your script code is missing a /  @luggagedonkey. If you change that closing script tag to </script> instead of <script> that should help.

there are so many programmer jokes about typos in code.  

that's my life.

THANKS!
