custom link does not work in drupal 6

In the drupal 5 version of the module I had added the following to hook_menu to create a 'my notifications' link on the navigation menu:

      $items[] = array('path' => "navigation/$user->uid/notify",
        'title' => t('My notifications'),
        'callback' => 'drupal_get_form',
        'callback arguments' => array('notify_user_settings_form', $user->uid),
        'access' => user_access('access notify'),
		'weight' => 5,
        'type' => MENU_NORMAL_ITEM,
      );

However, I try adding this to the drupal 6 version of the module:

  $items['navigation/%user/notify'] = array(
     'title' => 'My notifications',
     'page callback' => 'drupal_get_form',
     'page arguments' => array('notify_user_settings_form', 1),
     'access callback' => 'user_access',
     'access arguments' => array('access notify'),
     'type' => MENU_NORMAL_ITEM,
   );

And the link no longer appears. Any ideas why?
