XML Site Map | Subfolder problems | Help Please

I am a novice and am having problems producing a site map on a WordPress 3.0.1 install used as a CMS, pages only with no posts.

The site is of an adult nature (not hard core) and in attempt to stay legal I have made an entry / exit page which is on the root. I found I had to use three pages in order to use the menu buttons Enter and Exit.
When the visitor clicks enter they are then taken to a static home page in the subfolder ie ‘my-site.com/subfolder with links to the five other pages.

XML Site Map Feed is installed on on the site root ie ‘my-site.com’ which consists of just three pages. One static one for enter and one for exit.

The remainder of the site which is just five pages is in a subfolder ie’ my-site.com/subfolder’.

When I open the site map all I see is the three pages on the root ie ‘my-site.com’ and not the ones on the subfolder.

Any advice would be most gratefully received.
Please bear in mind I am a total beginer an have no coding skills, athough I did manage to paste in the tag for the Google verification but thats about my limit.
