Not sure if I'm posting this in the right section, and I'm totally new to Sitepoint and it seems like maybe someone here can help me out.

I've been maintaining a website for a client, and the header on the page isn't showing up on IE browsers. It works fine on Firefox, Safari, and Chrome though. I did not create the website, and while I have been maintaining the website with my self-taught dreamweaver skills , I'm afraid I've exhausted my already limited skill-set in trying to figure out how to make it work. Does anyone know why this might happen?

I've copied the code for the header below. Any and all tips are welcomed. My knowledge of html is limited at best, and I've been maintaining the website mainly with luck that it hasn't broken down completely on me. If anyone could simplify what I should be changing to make it work that would be helpful! Thanks!!
