OK I think I get most of it. Thanks
What I need a refresh course is about the actual header boxes what goes in where for best result.
Oh yes I need to put Google analytic code in and that should be in there too somewhere in one of the hearder boxes.
Thanks for your help.
Default Header:
HTML and PHP allowed.
Shows at the top of every page.
Header Insert (common to all):
Use for meta tags, etc. and will always be inserted in the <head> section.
If you have any description meta tag here, you should move it to the section below!
Header Insert (when not displaying a topic):
This will be the default used for any page that isn't a topic.
Otherwise, the <description> will derive from the actual topic contents for SEO purposes.
