Auto Follow Post Help

Here is what I want to do. Any time a user from user groups “Columnists” and “Contributors” changes their post status to “Pending Review” the user group “Editors” get a notification (auto follow the post).

Well I keep getting error Parse error: syntax error, unexpected ';' in /home4/josiahw/public_html/sandmag/wp-content/themes/flavor/functions.php on line 55

Here is what my themes functions.php looks like

<?php
/*
* Sets up the theme by loading the IndustrialThemes class & initializing the framework
* which activates all classes and functions needed for theme's operation.
*/

# load the IndustrialThemes class
require_once( get_template_directory() . '/framework.php' );

# get theme data
$theme_data = wp_get_theme();
# initialize the IndustrialThemes framework
IndustrialThemes::init(array(
	'theme_name' => $theme_data->name,
	'theme_version' => $theme_data->version
));

/**
 * Auto-subscribe or unsubscribe an Edit Flow user group when a post changes status
 *
 * @see https://editflow.org/extend/auto-subscribe-user-groups-for-notifications/
 *
 * @param string $new_status New post status
 * @param string $old_status Old post status (empty if the post was just created)
 * @param object $post The post being updated

 */
function efx_auto_subscribe_usergroup( $new_status, $old_status, $post ) {
    global $edit_flow;

    // When the post is first created, you might want to automatically set
    // all of the user's user groups as following the post
    if ( 'draft' == $new_status ) {
        // Get all of the user groups for this post_author
        $usergroup_ids_to_follow = $edit_flow->user_groups->get_usergroups_for_user( $post->post_author );
        $usergroup_ids_to_follow = array_map( 'intval', $usergroup_ids_to_follow );
        $edit_flow->notifications->follow_post_usergroups( $post->ID, $usergroup_ids_to_follow, true );
    }

    // You could also follow a specific user group based on post_status
    if ( 'copy-edit' == $new_status ) {
        // You'll need to get term IDs for your user groups and place them as
        // comma-separated values
        $usergroup_ids_to_follow = array(
                // 18,
            );
        $edit_flow->notifications->follow_post_usergroups( $post->ID, $usergroup_ids_to_follow, true );
    }

    // Return true to send the email notification
    return $new_status;
}
add_filter( 'ef_notification_status_change', 'efx_auto_subscribe_usergroup',

?>

I am not sure what to set or what I have wrong here.

Any help would be much appreciated. Thank you.
