error in IE

I have just updated the supersized script on a page i have designed, but i get errors in ie:
http://www.nordarchitects.dk/

link to supersized: http://www.buildinternet.com/project/supersized/

In IE 7 i get the following error message:
Line: 117
Char: 165
Error: Invalid argument
Code: 0

Has anybody got an idea how to fix this?

Thanks
Simon
