Nope, I don't think you must be doing this correctly. If you search the forums there are posts on how to create a sitemap.
But basically you use that website I gave you to create it then you save it as a download to your pc. you save it as 'sitemap.xml'
Then go into FTP via the BV tool and drag it into your public_html folder.
Rename your link
http://www.maravillamountain.com/sitemap.xml and it should work.
