Problem with Moveable type in Internet Explorer

On my website I used Moveable Type for the blog entries and management. Everything works fine in both IE and Firefox, apart from the viewing Individual entries. There are no apparent problems with the code, and it works fine in Firefox, though in IE it's totally messed up.

An example of an individual entry page:

Obviously I'd like to fix this, so it can be viewed in IE because a large proportion of my visitors use Internet Explorer.

Any help is greatly appreciated.

Bump for help...

Give your code a run through the validator, http://validator.w3.org/.

The main issues seem to be that your comment tags are incorrect and you have multiple occurences of the same id for several elements.

Your comments should look like:
<!--NAV-->
Not this, note the extra !:
<!--NAV--!>

Only one element per page can have a given id. If you need to apply the same set of styles to multiple elements use the class instead.

Thankyou so much for your help, that solved the problem.
