script doesn't seem to work on my server, should it?
my demo on my server.
Uncaught ReferenceError: $$ is not defined
Your mootools files aren't loading
Man you guys make me feel dumb
Instead of feeling dumb about things, you may then want to learn about how that information was found.
When I loaded the non-working page in Google Chrome, I presses Ctrl+Shift+J to bring up the scripting console. You can do similar in Firefox as well, especially when using the Firebug extension.
Anyway, that's where I saw the problem concerning $$, and also info about how those script files didn't exist.
