Added a html portal box and by buttons disappeared?

[VintageJetBoats]

On my portal page at www.vintagejetboats.com I added an html box with the following code for youtube videos and somehow it disables my buttons on the top of the page.
Any ideas on what the problem with this code might be?

I am using this
 
   <img src='http://img.youtube.com/vi/a3aj2ZEzmtk/1.jpg' width='130' height='97' border='0' class="yt-img" alt='a3aj2ZEzmtk' title='Video screenshot' /> <img src='http://img.youtube.com/vi/4TLX9EHRQyk/2.jpg' width='130' height='97' border='0' class="yt-img" alt='4TLX9EHRQyk' title='Video screenshot' /> <img src='http://img.youtube.com/vi/0r_ajyFyRAc/3.jpg' width='130' height='97' border='0' class="yt-img" alt='0r_ajyFyRAc' title='Custom title' /><br /><br />
<iframe id='youtube-player' type='text/html' width='640' height='385' src='http://www.youtube.com/embed/oGyk8xBVQIE' frameborder='0'></iframe>   
    <script type="text/javascript" src="http://www.google.com/jsapi"></script>
    <script type="text/javascript">
      google.load("jquery", "1.4.4");
      google.setOnLoadCallback(function() {
          $('.yt-img').bind('click', function(event) {
            newurl = "http://www.youtube.com/embed/" + $(this).attr("alt");
            $("#youtube-player").attr("src",newurl);
          });
      });
    </script>

Ok so I got it fixed up and it's working but, for some reason it's not randomizing. When I use the code on a regular web page like this one www.vintagejetboats.com/jeffindex.php it will bring up random videos each time. Is the something with the cache that's not allowing it to do the randomizing?
