It looks like you did not do the bindings correctly. You only included the html, but no the value of the form elements.
When you click the DW Edit button, open the Bindings Panel by going to Window -> Bindings in Dreamweaver. And then expand the form entry (for example, it might said something like "SimpleContact_NewFormBlank_..."), and under it you will see the bindings, such as the name, email and comments. Then drag each one of those to emailbody box.
I have attached a sample of how your Universal Email page should look like.
