Warning: call_user_func_array() expects parameter 1 to be a valid callback, func

Hi all,
I have created a child of html5 blank theme in localhost with xampp.
In the functions.php folder is:

<?php
function html5blankstablechild_scripts() {
wp_enqueue_style( ‘html5blank-stable-child-style’, get_stylesheet_uri() );
wp_enqueue_script( ‘html5blank-stable-child-hd.jquery’, get_template_directory_uri() . ‘/js/hd.jquery.js’);
wp_enqueue_script( ‘html5blank-stable-child-jquery.easing.1.3’, get_template_directory_uri() . ‘/js/jquery.easing.1.3.js’);
wp_enqueue_script( ‘html5blank-stable-child-jquery.prettyPhoto’, get_template_directory_uri() . ‘/js/jquery.prettyPhoto.js’);
wp_enqueue_script( ‘html5blank-stable-child-jquery-1.6.1.min’, get_template_directory_uri() . ‘/js/jquery-1.6.1.min.js’);
wp_enqueue_script( ‘html5blank-stable-child-layers’, get_template_directory_uri() . ‘/js/layers.js’);
wp_enqueue_script( ‘html5blank-stable-child-tooltips’, get_template_directory_uri() . ‘/js/tooltips.js’);
}
add_action( ‘wp_enqueue_scripts’, ‘html5blank-stable-child_scripts’ );

When I view the site I get the following error message:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘html5blank-stable-child_scripts’ not found or invalid function name in C:\xampp\htdocs\wordpress\wp-includes\class-wp-hook.php on line 286

On the above mentioned line of C:\xampp\htdocs\wordpress\wp-includes\class-wp-hook.php is:

$value = call_user_func_array( $the_[‘function’], $args );

I have no coding experience and would appreciate anyone helping me to resolve this issue.
Many thanks in advance
