WooCommerce child Theme Error

Hi I am using wooCommerce for the first time . I am using the storefront theme and trying to add my own child theme(css file) but it will not work correctly.

I have added it in my setup.php functions file

function storefront_child_scripts() {
    if ( is_child_theme() ) {
        wp_enqueue_style( 'storefront-child-style', get_stylesheet_uri().'/custom-child.css', array('parent-style'), '1.0.0' , 'all' );
    }
}

I have also added what i believe to be the right syntax to the css file..

/*

*/

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

When i inspect it in my browsers it shows in the very top of the head but not correctly and the browser cannot seem to find it. I also find it strange that it loads at the top of the head when its soppose to be loaded last . I shows as...

<link rel="stylesheet" type="/custom-child.css" href="mystyle.css">

As you can see this is completely wrong the href points to 'mystyle' which I have no idea where that came from and the type shows the name of my file .

If any body has any experience with this and is willing to help would be great. Thanks
