Sidebars are gone when I switch to my new custom template

[chrysalid]

Hello!

I just installed Zen Cart 1.5.
I'm using it locally until I get it all setup - I haven't uploaded it to my web site yet.
I bought the eBook "Zen Cart 1.5 Step by Step by David Ipswich" and have followed the first few instructions.
He advises to go through and copy/paste/rename a bunch of 'classic' folders with 'custom' folders.
After doing this, and changing my template from classic to the custom one I've created, I end up losing much of my layout.
The size bars are gone.
I've attached an image of what I end up with.
After this happened, I went back and started from scratch again, but still end up with the same result.
Any advice on how to fix this?

Thanks!
Amber
