Blogger settings

I solve this problem so: into function blogger_menu() add:

      $items[] = array(
      'path' => 'admin/blogger/settings',
      'title' => 'Bloger settings',
      'description' => t('Manage blogger settings'), 
      'callback' => 'drupal_get_form',
      'callback arguments' => 'blogger_settings',
      'access' => user_access('access blogger'),
      'type' => MENU_NORMAL_ITEM
    );

And replace a few strings above: return $form; to return system_settings_form($form);
