Child Theme not visible after set-up

Hi,
I followed this guide to get a child theme up and running, but it doesn’t appear in Appearance > Themes to activate. I’ve tried logging in again, but the theme still doesn’t appear.

Here is my style.css…

/*
Theme Name:     Oulu Red Cross
Theme URI:      http: //www.oulunosasto.fi/
Description:    Customisation theme for Oulu Red Cross member site. Uses twentyeleven from WordPress as parent.
Author:         Sennomo
Author URI:     http: //notsure.co.cc/
Template:       twentyeleven
Version:        2011.11.19
*/

@import url("../twentyeleven/style.css");

#site-title a {
    color: #D81E05;
}

…the path is, public_html/wp/wp-content/themes/twentyeleven/twentyeleven-child/style.css

I can’t see the new theme to activate it. What have I done wrong here?
