title: Tweenlite - a sequence chain of TweenLite.to not triggering
body: <p>Its pretty simple what im trying to achieve.
  I have a MC on Stage, which im trying to tween to different X coordinates.</p>
  
  <p>I've set up four TweenLite.to sequences, however for some weird reason only one is being triggered - what am I doing wrong?</p>
  
  <pre><code>TweenLite.to(slider.mc_slider,1,{x:_returnXPos(95), ease:menuEasing});
  TweenLite.to(slider.mc_slider,1,{delay: 1, x:_returnXPos(35), ease:menuEasing});
  TweenLite.to(slider.mc_slider,1,{delay: 2, x:_returnXPos(50), ease:menuEasing});
  
  //Function which returns x coordinate of Sliderbar - related to defined percentage
  function _returnXPos(definedPercentage:Number):Number {
      var defineWidth:Number = slider.mc_background.width * (definedPercentage/100);
      return defineWidth;
  }
  </code></pre>
