Javascript issues

Hi, I'm hoping you can help me here. I have a website I've been working on and it seems to have some javascript issues that only appear when using Internet Explorer. Would you be interested in taking a look and fixing them? The website is [login to view URL] The issues im having happen on the events calendar page (link is in the menu at the top). Each event listed should link to the next page but the link doesnt work in IE. Check it in another browser to see how it should work. The other issue is with the photo gallery (link in top menu). The links should open up a photo gallery but doesnt work in IE also. Once viewing a photo gallery the images are clickable to view larger. This doesnt work correctly also. These issues are only happening with IE. All other browsers work exactly as they should.
