What is wrong with my jQuery / my JS?
<p>I just started working on the following site: <a href="http://www.psykotaktyle.com/" rel="nofollow">http://www.psykotaktyle.com/</a></p>

<p>I have downloaded the latest jQuery (1.6.2) and jQuery UI (1.8.14).</p>

<p>The only other JS code on the page is:</p>

<pre><code>function get_url_param(param, url) {
  param = param.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&amp;]"+param+"=([^&amp;#]*)";
  var regex = new RegExp(regexS);
  var results = regex.exec(url);
  if( results == null )
    return '';
  else
    return results[1];
}

$(document).ready(function() {
  $('ul.menu li').click(function() {
    var href = $('a', this).attr('href');
    var content = get_url_param('page', href);
    if (!content) content = 'home';

    $('.slide-item').animate({top:'1000px'}, 500)

    //$('#content').fadeOut();

    //alert(content);

    return false;
  });
});
</code></pre>

<p>For some reason I get a JS error on the page when clicking on a menuitem.</p>

<blockquote>
  <p>Uncaught TypeError: Not enough arguments jQuery-1.6.2.min.js:18</p>
</blockquote>

<p>I don't have a clue what went wrong here so I hope someone can tell me what is causing this error.</p>
