Custom Template is not working

Hi
I have been working on the home page of my website, and I’ve almost got it where I want it. But when I tried to make an additional page it does not look anything like my original page. I assume I would call up “custom Template” in the attributes drop down, but this does not change anything.
I don’t know if my custom.css is done wrong, or if there is some piece of PHP code I’m missing. Or do I have to create a custom template like Berchman said here. Thesis Tutorial: Multiple Custom Page Templates ? berchman.com
I’m very new to all this, but I’m sure this should be very easy. Which means it has to do with my code.
