   Hello Guru's!

   I'm building an event custom post for a website using various tutorials out there. I've got everything I need including a metabox with a date. Although instead of a date field its giving me the following error:

   Warning: call_user_func(agenda_meta_options) [function.call-user-func]: First argument is expected to be a valid callback in /home/deb45722/domains/goforthatjob.nl/public_html/wp-admin/includes/template.php on line 963

   I have built an agenda custom post for another website before using the same tutorials and that worked. But it was a long time ago and I can't remember if I had to put in a hack somewhere to show wordpress this is a valid fuction. I also can't find a lot of information about this online using google.

   Anyone know what this means?

   Heres the code for my metabox:

   //BEGIN METABOX
   add_action('admin_init', 'register_agenda_meta');
   
   function register_agenda_meta()
   {
     add_meta_box('agenda_options', 'Item datum', 'agenda_meta_options', 'agenda', 'side', 'high');
   }
   
   function event_agenda_options()
   {
     echo "<label for='start_date'>Start:</label><input type='text' name='start_date' value='' />";
   }
   
   ?>

   The third argument of add_meta_box must be a valid callback function name: try it with:
   

   add_meta_box('agenda_options', 'Item datum', 'event_agenda_options', 'agenda', 'side', 'high');
