First things first. You haven't declared a valid doctype, which IE, and all browsers for that matter need if you expect cross browser compliance.
Second, you have quite a few coding validation errors. You should validate
often throughout the coding phase to ensure clean code. Many of your errors, besides the doctype, is that you have multiple id's with the same name. ID's must be unique, whereas classes can be the same.
Fix those errors and then see how it renders in IE. btw, dont rely on DW's browser view to accurately display a webpage. Test in ALL modern and some older browsers.
Finally, I would suggest you read about divitis
. You dont HAVE to wrap every element in a div. Many elements are already grouped together and can thus stand on their own.
I recommend that you head over to w3schools.com
and start working through their html/css tutorials for a better basic understanding of code.
Hope this helps
