It's really weird, with the original error that you mentioned yesterday, I couldn't see that the Page.ss was missing any div tags but when I added an extra div it fixed the home page error.
Trouble is, I am used to dealing with a single page of XHTML in it's entirety for each web page I want to create, not parts of pages brought together into one final page. This is probably where I am getting a bit mixed up. :-(
A good night's sleep and fresh eyes and I have fixed the problem. Went through all the code and commented start and finish of each div. I picked up on a couple of errors and it all seems to be working well now :-)
