Popup not showing

Hey,

I can't seem to get the popup plugin to work. I have it installed and edited to work on a site-by-site basis. I'm trying to run it on rantsports.com/redzonetalk/. I'm not even seeing the files showing up in Firebug for the popup to work. I'm running a cache plugin and have cleared it several times.

Any suggestions would be great!

Thanks
Grant
