dreamweaver, ssi, and templates

what am i doing wrong!

Hi all.

I'm just now forcing myself to learn templates and I'm also trying to add ssi to my list.

Deal is, I've got this site that I'm doing for someone and I'm kinda using it to "experiment"

What I've done so far...
made a table in a document labled nav.htm that contains my nav bar.

made a template file that contains an ssi referring to the nav.htm doc. and 1 single editable region for content.

made a page called index.htm and applied the template to it.

Well...
When I did that last item the ssi nav bar showed up just fine (in dreamweaver) so I added some gibberish to the editable regiong.

Now, when I test it (in the browser, on the server or from DW) only the editable region with the gibberish shows up. Where did my nav bar go?!?!

Help?

Thanks.
