editing HTML Inserts: Header

I am trying to add the following header to my wordpress. But I'm hitting my head against the wall trying to find the best method of adding the header.

This is the site, it's a test site for my main site:

http://www.walama.com/

And I am trying to add the following header from my main site:

http://www.thefwoosh.com/header/New folder/header_2009.php

but I'm not succeeding.

I am getting the header in by copying the code from the above php file into Atahualpa Theme Options > HTML/CSS Inserts > HTML Inserts: Header. But I'd rather just link to the php. I've tried php include and iframe with mixed results.

Any ideas?
