Created child theme but doesn't work

Hi,

I created a child theme for twenty twelve but it doesn’t work properly, like the layout and stuff.

This is what I have in the style.css file I created for the child theme:

/*
Theme Name: Twenty Twelve Child Theme
Description: Child theme for the twentytwelve theme
Author: Meenimod
Template: twentytwelve
*/

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

edit: fixed, spelling mistake.
