[jQuery] Cycle Lite not working in IE

I'm using Cycle Lite in two places on this site, to rotate through the
testimonials on the homepage, and to step through the photos on the
contact page with prev next links. The contact page works fine, but
the homepage is not working at all in IE. I tried adding overflow:
hidden to the container, but all that does is stop the extra content
from spilling out over the rest of the page. But still no cycling.

Any ideas? The site is http://carstar.lsquareddesign.ca
