Site map help

Gurus,
I need a little help. I am trying to make a site map for one of my sites. I figure if I can figure out how to do one, I can do many. My problem is that google reports errors but doesn't specify what the error is. Can you see anything wrong with this file. I call it ntas_config.xml and put it in the root directory. The site is verified by google. I cleaned out some of the page links to make a smaller posting.
Thanks
Craig

Hi,

I just created your google XML file, using xml.sitemaps.com all you need to do is upload it to google sitemaps, you may need to copy it and paste it onto note pad and save it as a XML file
