Themes

I'm new to Tikiwiki and I am currently working on the theme for the site. I really liked Kubrick's theme and just tweaked the header images a bit to fit my site. The problem is that the theme shows just fine when I am in the admin part of the menu, but as soon as I click "home" under main menu, the header and footer don't show. Is there a template I have to change or did I forget to do something when I set the theme?
