That's odd, that should have done it.
Just to be sure we're doing the same steps, here's what I would normally do. Again, apologies if this is what you have already tried.
In Dreamweaver, open your local site that has all the Powerstore folders and files in it. If you haven't created a local site for these in Dreamweaver, then you can just quickly create one now.
Then follow the steps in my last post. When you have made changes to your main template page, and click 'save', Dreamwever should ask you if you want to update all the other pages based on this template. Click OK.
DW updates the other pages with your changes. You then need to re-upload all the changed pages to your remote server (you don't need to upload the template, but it's fine if you do).
