title: Javascript error when sharing with LinkedIn Share API
body: <p>I have the following code: </p>
  
  <pre><code> $(".btn_li").click(function() {
      window.open("http://www.linkedin.com/shareArticle?mini=true&amp;amp;url='+document.URL+'&amp;amp;title=Webpage Title;summary=Webpage Summary", "LinkedIn", "width=660,height=400,scrollbars=no;resizable=no");
  try { 
   _gaq.push(['_trackEvent', 'Social', 'LinkedIn', "Page URL"]); 
   } catch(err){}        
  return false;
  }); 
  </code></pre>
  
  <p>and call this from: </p>
  
  <pre><code>&lt;div class="btn_li"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>When this button is clicked, the LinkedIn error I receive is, "There was an unexpected problem that prevented us from completing your request." This tells me that the parameters are not being passed correctly. </p>
  
  <p>Any advice? </p>
