New Child Theme

I am using wordpress and trying to create a child theme page. Do you know how to do this? I have been trying to follow the directions but seem to be stuck.

I have gotten as far as getting it to show up on the themes page where it tells me it is missing the “twentytwelve-child Stylesheet is missing”.

I have been working on this since this morning and I’m sure I’m missing something simple.

So far:
1.) I’ve created a folder in my website File Manager and named it with the same name as the template theme I’m using ie: twentytwelve with new file twentytwelve-child.

2.) I’ve coped the code from wordpress and filled in my info:
/*
Theme Name: Twenty Twelve Child
Theme URI: http: //mysite.com/
Description: Twenty Twelve Child Theme.
Author: My Name
Author URI: http: //mysite.com/
Template: twentytwelve
Version: 0.1
*/

@import url(“../twentytwelve/style.css”);

3.)created a text file containing the style.css codes from the twentytwelve theme.

Question: do I need to reference the style.css code file someplace in the above code or…. I’m lost. It says it’s supposed to be easy but….

Please help.

Thanks.

Paul….
