Stopped working on the home page

For some reason the shadowbox js plugin that is download & linked on the sidebar is not working on the home page. However, it works on every other page. Do you have any idea what would cause it not to work on one page, but works on all the others? This just recently occurred. I uninstalled the plugin & reinstalled it & that didn’t do it. It is the 2 links under View Our Demo Reals, Health & Science and Sports & Leisure.
