Dynamic site - only homepage is indexed in sitemap.xml?

[chidog]

I used the free sitemap generator for my static site before.  Recently, I redesigned the entire site to dynamic pages.  When I use the free sitemap generator to generate a new sitemap, only the homepage is added to the sitemap.  My site is: [external links are visible to admins only] and the sitemap generated is like this:

<?xml version="1.0" encoding="UTF-8"?>
<urlset
      xmlns="[external links are visible to admins only]"
      xmlns:xsi="[external links are visible to admins only]"
      xsi:schemaLocation="[external links are visible to admins only]
            [external links are visible to admins only]">
<!-- created with Free Online Sitemap Generator www.xml-sitemaps.com -->

<url>
  <loc>[external links are visible to admins only]</loc>
</url>
</urlset>

How do I add the dynamic pages to the sitemap and let Google know that my site is more than 1 page?
