My website is not working

Hi I used some jquery effects to create my website. The text slides to the right when it changes page. It is working fine in firefox and safari, but in internet explore it doesn't work.

here is the url of the page on my website that doesn't work in internet explore: http://katieduck.com/Courses/Improvisation Winter Course Dartington.html

Maybe you can see what is wrong,
thank u,
