Errors on IE - Object doesn't support this property or method

Hello everyone,

I'm trying out JQuery and have created a modal login based pretty much on simplemodal examples.

This all seems to work fine on Firefox 3.6, Safari 4.0.3 but on IE 8.0 I;m getting javascript errors and the login modal doesn't launch. Also my javascript slideshow seems to not work on this particular page.

These are the errors I'm seeing:

Here is the page itself: http://bit.ly/dtvxGB  The login is triggered by clicking on the MS Word icon.

Any hints would be appreciated.

Thanks
