Trouble with internet explorer 7

Trouble with internet explorer 7

Hi - wondered if someone might be a ble to take a look at my site which is nearly ready to go live?

It's working well in all browsers apart from internet explorer 6 / 7 . I'm not even going to try to support 6 so let's just worry about 7 - this is driving me insane!

It uses quite a few jquery plugins and loads jquery and jquery tools through the jquery tools cdn. The trouble is that in ie 7 the javascript doesn't work properly and means the page is useless! I tested it using firebug and no error came up but then I tested it using browsera and IE throws the error saying that jquery is undefined. At first I assumed that this was a problem with the order the various external js files were loading but jquery is first on the list of things to load.

I'm stumped so any help would be great! The url I'm testing on is
