Custom Header

Hi there,
I am using some custom header code and all works well until you try and click on a blog entry from the recent comments/posts link or the calander link. Then it seems teh file paths dont work properly.
I have changed the flash links over to absolute filepaths which should negate the filepathing issues however htat is what it seems to be when you look at the compiled page — that is the flash banner doesnt compile.
Any thoughts — i will gladly post code if requested.
