[jQuery] cross-slide in IE7

[jQuery] cross-slide in IE7


Please forgive my inexperience, I am a designer trying to take over
the development!
These 2 sites I created using cross-slide and it doesn't seem to work
in IE7:
http://nirmada.bigrigmedia.com/portfolio/
and
http://horizonrvresorts.bigrigmedia.com/
Please help, THANK YOU!
