Creating a Child Theme – difficulties

I have looked at previous posts on this and cannot see any obvious mistakes in my CSS code but still saying Template missing when I go to activate it. The site is: http://sirmoor.2ndgoorkhas.com/ it will be a renewal of a site built in Serif WebPlus. Built for charity (I am a newbie to WordPress so likely to be asking quite a few questions I am afraid as I was volunteered to do all their sites for free and have had to learn everything from scratch,)
Code I am trying to use for the child theme below:

/*
Theme Name: mh-magazine-lite-child
Theme URI: http: //mysite.com/
Description: This is a custom child theme I have created.
Author: my Name
Author URI: http: //mysite.com/
Template: mh-magazine-lite
Version: 0.1
*/
@import url(“../mh-magazine-lite/style.css”);

Using my FTP I have loaded the CSS script above in the following folders ie
Themes
-index.php
-mh-magazine-lite
-mh-magazine-lite-child
– style.css
into the style css of the child folder is the following code:
I keep getting the error message saying stylesheet is missing.
I have been puzzling this for over three weeks and cannot get the child theme to work and it is important that I get the child theme to work.
Please any suggestions on this.
(I have posted this before but did not get an answer to this. Some say that creating a Child Theme is easy and yet getting an answer has proved very difficult.
Many thanks
