I’m having trouble getting Help tabs to show up on my settings page for my custom post type. I’ve gone through the Demo, and replicated it appropriately (I think), but still no luck.

Here’s the code creating the CPT

add_filter('piklist_post_types', 'listing_post_type');
 function listing_post_type($post_types){ 
 $post_types['listing'] = array(
	'labels' =>piklist('post_type_labels','Listings')
     ,'title' => __('Simple Business Listings')
 ,'public' => true
	 ,'admin_body_class' => array (
        'listing-admin'
       
      )
 ,'has_archive' => 'true'
	 ,'capability_type' => 'post'
	// ,'taxonomies' =>'post_tags'
	 ,'rewrite' => array(
 'slug' => 'listing'
		 
 )
 ,'supports' => array(
 	'title',
		'author'
,'revisions'
	 
		,'editor'
		, 'excerpt'
		,'thumbnail'
		, 'comments'
		
 )
  ,'status' => array(
     'draft' => array(
       'label' => 'Draft'
     )
     ,'premium' => array(
       'label' => 'Premium'
     )
     ,'basic' => array(
       'label' => 'Basic'
     )
   )
 
  );
return $post_types;
}

And here’s the code for my help page.

<?php/*
Title: Using the Custom CSS
Capability: manage_options
Page: listing, listing_page, listing_page_directory_settings
*/
?>

Any suggestions?
Thanks
