Your Sitemap does not appear to be in a supported format. Please ensure it meets our Sitemap guidelines and resubmit.

 

Submitting a sitemap is different from submitting an html index page.

Google uses XML sitemaps: https://www.google.com/webmasters/tools/docs/en/protocol.html

If you don't want to bother with making a sitemap, you can just submit your html here: http://www.google.com/addurl
