title: Jquery Animate callback running several times. Why?
body: <p>Here I am with my first post. My issue is that the callback function of my main animate isn't running one time as it is suppose to, but severeal times (7). I do not understand why. 
  Thank you in advance for your replies. Cheers. Marc.</p>
  
  <pre><code>$('#wrapper li').click(function(){
  
     //Here I declare my varaiables
  
     $('#wrapper li').slice(startLi,endLi).animate({
              "left": '-='+leftDistance},
              "fast",function() {
                      $('.class').animate({
              "left": "+=200px"},
              "slow");
     });
  });
  </code></pre>
