I don't have those files in the mysite directory only in the event_calendar directory.

Well that fixed the problem in firefox but it's still not displaying correctly in IE. The Upcoming Events are not are not displaying correctly on the Calendar page in IE either. It looks great in firefox but not IE. Any ideas?

Getting pages to look right in IE is the bane of every web developer's existence. Unfortunately, this isn't really a forum for CSS and XHTML support. You can probably post your link to HTMLForums or WebMasterWorld and get some good tips. I can take a look if you have a link, as well.

A lot of times, you just have to make an IE specific stylesheet and put it in conditional comments to target the browser.
