Stuck on Task 4 of 6 quiz

The quiz hinted " The first thing inside the widget method, use the extract function to make $args into local variables."

But I have already used the extract($args) function like in the video. What's wrong?

plugin.php 
<?php

    class My_Plugin_Widget extends WP_Widget {

        function my_plugin_widget() {
            parent::__construct( false, 'My Plugin Widget' );
        }

    function widget( $args, $instance ) {
        // Widget output
        extract($args);
        $title = apply_filters('widget_title', $instance['title']);

        require('inc/front-end.php');
    }

    function update( $new_instance, $old_instance ) {
        // Save widget options
    $instance = $old_instance;
        $instance['title'] = strip_tags($new_instance['title']);

        return $instance;
    }

    function form( $instance ) {
        // Output admin widget options form
    $title = esc_attr($instance['title']);
        require('inc/widget-fields.php');
    }


    }



?>

Hi Chris, You actually have two problems. One is a problem that seems like an anomaly. That is that for some reason the comment is causing an error. If you delete the comment, you'll get rid of your error message about the extract function. However, then you will have another error. You've included a statement:

 require('inc/front-end.php');

which is not called for in the instructions. If you delete that line too, all should work. Good luck! Richard
