Don't take the line number seriously, this would be the compiled line number rather than the file line number. I suggest you remove parts of your Page.ss template until it works again. Once it starts working you'll know what code is causing the error.
Check your template for syntax errors. Make sure all tags are closed, all variables are marked correctly, and all quotes are the correct ones (none of those "smart quotes" if you've copied code from anywhere) and closed with matching quotes.
If you're using a program that highlights code, you can usually set it to recognize .ss files as HTML, which will provide code highlighting for the parts it recognizes, making it easier to spot errors.
