How do I make a div editable, saving page as .dwt

[mulletgut]

I am using one of the templates from dreamweaver (albeit with a lot of changes)which uses all divs for layout. I wish to make many pages based on this layout with just a couple of editable regions. I have a banner, and a left nav menu and wish to put a main content editable area beside that in the centre of the page and a narrower editable area on the right of the page. There are already divs for these areas which are quite cool where they are, however when I save the page as a template, and then open a "new" page based on this template, I can't edit anything in those areas. Will I have to scratch the css idea and resort back to tables?I do like css, so much to learn. I shall go do more tutorials to try to sort this, would be happy if there was a simple way to do this.Thank you for your time.
