Need Joomla freelancer to help with script errors.

My website is built in Joomla 1.5. I am having several problems with several components, mostly script problems. I use the component JEvents so that visitors can upload upcoming events to my calendar. However, the 'add events' screen doesnt work in Internet Explorer. It works fine in Mozilla, but in Internet Explorer an error message pops up and doesnt allow people to proceed to the page where they can add events. Also, it is sized wrong. It takes up too much of the screen. The 2nd problem I am having is with a component called Joomla stats. The program is a simple stat tracker. It works, but none of the links on the page work. An error message pops up when clicked on. So I cant see referrals, previous months etc. Any help would be greatly appreciated, and could lead to more work for the right person. Thanks.
