哎哟，我的头撞到墙上了！

我正在尝试在索引中查询我的帖子类型“clips”。php，但它只返回默认“post”中的post。我需要一些洞察力！我做错了什么？

我的帖子类型：

$args = array( 
    \'labels\' => $labels,
    \'supports\' => $supports, 
    \'hierarchical\' => false,
    \'menu_position\' => 4,
    \'publicly_queryable\' => true,
    \'show_ui\' => true,
    \'public\' => true,
    \'query_var\' => true,
    \'capability_type\' => \'clip\',
    //\'map_meta_cap\' => true,
    //\'capabilites\' => $capabilities,
); 

register_post_type( \'clip\', $args ); 

<?php query_posts(array(\'posts_per_page\' => 17, \'post_type\' => array(\'clip\'))); ?>

<?php if (have_posts()) : ?>

<ul id="clips" class="clearfix reset">

  <?php while (have_posts()) : the_post(); ?>

    <li>
      <?php the_title();?><br><?php the_permalink(); ?>
      <a id="post-<?php the_id(); ?>" class="videolink" title="Click to view" href="">
      <?php if ( has_post_thumbnail() ) { 
         the_post_thumbnail(); 
        } else { 
        echo "No thumbnail"; 
        } ?></a>
    </li>

   <?php endwhile; ?>

    </ul>


    <?php else: ?>
