Modify>Template>Apply Template to Page
These are on your dreamweaver menu bar at the top of Dreamweaver.
This opens the Select Template dialog box. Select your template.
Dreamweaver then asks you to match editable areas. For example body; head; match your regions to theirs. Click okay. This will add your template to the SA pages...
Do this with every page. Save each page after applying the template.
Hope this helps...
