Help with creating a new template

So I edited the classic template to how I wanted to look but then I read that I'm not supposed to edit the classic template, so I copied the files from the classic template into a new folder in the templates folder and put the original classic files in the classic template folder but when I select the template that I made nothing shows! If I move my template back to the classic folder it works fine, but not in it's own folder. Help please!

It's actually not showing any other template than the classic one...

Did you copy the template_info.php file into your new template and edit the info in it to reflect your new template name?

Change:
$template_name = 'Classic Contemporary Green';

to:
$template_name = 'New Template Name';

OK I fixed it. I had to restore the template to the original form and then I follow the directions on making a new template. Thanks for the help.
