Child theme not working.

Hello.

I edited a complete theme, but now I’d like to set it in a child theme.
Had I just done it at the start…. right?!

Now I have a problem with the child theme.
Wordpress tells me that there is an error with the theme:

Damaged theme:

Template missing.

I did all the things I could find to make a child theme (as far as I can see it should be only the style.css, right?).

This is my style.css:

/*
Theme Name: Responsive child
Theme URI: http://cyberchimps.com/responsive-theme/
Description: Responsive Child theme
Author: M.Kort
Author URI: http://cyberchimps.com
Version: 1.0
Tags: white, black, gray, light, custom-menu, custom-header, custom-background, one-column, two-columns, left-sidebar, right-sidebar, theme-options, threaded-comments, full-width-template, sticky-post, translation-ready, rtl-language-support, responsive-layout, fluid-layout
Text Domain: responsive
*/

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

This should be all there is right? What am I doing wrong?
Thanks!!
