    Hello All,
    I recently followed this tutorial on doing custom comment styling.
    Advanced WordPress Comment Styles and Tricks
    I keep getting: Warning: call_user_func(advanced_comment) [function.call-user-func]: First argument is expected to be a valid callback in /home/*******/public_html/*******/wp-includes/comment-template.php on line 1336.
    I am not sure why I am getting this error, I followed the tutorial step by step. Thank you in advance for any help :)
    Here is my code (trying to put in backticks):

    	// Add RSS links to <head> section
    	// Load jQuery
    	if ( !is_admin() ) {
    	   wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"), false);
    	// Clean up the <head>
    	function removeHeadLinks() {
        	remove_action('wp_head', 'rsd_link');
        	remove_action('wp_head', 'wlwmanifest_link');
        add_action('init', 'removeHeadLinks');
        remove_action('wp_head', 'wp_generator');
    	// Declare sidebar widget zone
        if (function_exists('register_sidebar')) {
    'before_widget' => '',
    'after_widget' => '',
    'before_title' => '<h4>',
    'after_title' => '</h4>',
    'before_widget' => '',
    'after_widget' => '',
    'before_title' => '<h4>',
    'after_title' => '</h4>',
    'before_widget' => '',
    'after_widget' => '',
    'before_title' => '<h4>',
    'after_title' => '</h4>',
    )); */
    //this function will be called in the next section
    function advanced_comment($comment, $args, $depth) {
       $GLOBALS['comment'] = $comment; ?>

    Almost forgot, if this helps any. Line 1336 from comment-template.php:

    if ( !empty($args['callback']) ) {
    	call_user_func($args['callback'], $comment, $args, $depth);
