Bit confused about Sitemap.xlm

I want to ad a site map to my website however I am a little unsure as to its contents.

Basically I have a simple site with only 5 pages, the site uses a navigation bar which is generated from a master page and is therefore visible on every page.

This means every page is navigatable from very page. In addition some pages also link to the other pages through key words in the text.

So back to the site map.

Do I create a one node site map where the primary node is my homepage with 4 sub nodes for the other pages
or
Do I just create a simple 5 node site map one for each page
or
Do I create a five node sitemap each page with 4 sub nodes for the other pages accessible from that page?
Im guessing not this one as a valid site map apparently does not have duplicate URLs, so in that case its one of the top two?

In addition, I completed a site map using the visual studio format including title and description properties, then when I tried to upload it to Google webmaster tools was told it was not in the correct format.

I tried the file as web.sitemap and sitemap.xml but google was having none of it.

Fishguy, I am not sure what you are referring to?!?

Which google tool are you using?

The sitemap format for the web.sitemap is unlikely to be the same format that google uses. It is in a format that ASP.Net understands.

What exactly are you trying to do?
