Script Error

I have gotten a script error a couple times when coming to the site that i thought I'd let you guys know about. This time I actually copied the script error but I'm not sure if it's the one that comes up each time (such an immediate reaction just to hit stop and keep going) Not sure if it's the site or something on my computer not playing nice, but it only happens when I visit the page. I have Firefox 17.0.1. Hope it helps.
