I have javascript for a lightbox element (which uses the prototype.js script) and slider element on the same page here: http://iphonemerchants.com/videos/

The scripts work perfectly when separate on other pages, but they seem to conflict when called at the same time. I am very novice at JS so I can't figure out how to interpret the Console JS errors.

If anyone would take a quick look at the errors and give me a suggestion, it would be GREATLY appreciated. This is the last problem I have to solve before my site can launch.

Thanks so much
