Code Challenge: How to Create a WordPress Shortcode

"Inside of the my_plugin_shortcode function, pull in the global post variable. Then extract the num_courses attributes, setting it to a default value of four."

Hi it gives the following error:

Bummer! extract should be passed the return value of shortcode_atts directly.

<?php
function my_plugin_shortcode( $atts, $content = null) {

    global $post;

    extract ( shortcode_atts( array('num_courses' => '4'), $atts) );
}

?>

Check the spacing after the extract function

ok I got rid of the space after the extract function call.... it looks like the wordpress coding standards say not to have a space there... http://make.wordpress.org/core/handbook/coding-standards/php/
