The script is not supposed to work with that doctype. It produces HTML code, not XHTML code.
Also, the script uses eval to find elements instead of document.getElementById, which only works in IE and browsers that try to emulate it. The eval function has it's rare uses, but this is not a good use of it. I am surprised if you only have that single problem that you describe.
