title: Concatenate in actionscript not showing symbol
body: <p>I have this flash program which is supposed to calculate the tip of a bill depending on the rating that you give it. In my Tip Percentage box I tried to have it concatenated to show the corresponding value + a percent symbol but the percent symbol is not getting displayed; only the value is there. Below is the code</p>
  
  <pre><code>import flash.events.MouseEvent;
  
  var tipTotal:Number = 0;
  var split:Number = 0;
  var tipPercent:Number = 0;
  var bill:Number = 0;
  var eachShare: Number = 0;
  
  oneStar.addEventListener(MouseEvent.CLICK, percentPopUp);
  twoStar.addEventListener(MouseEvent.CLICK, percentPopUp);
  threeStar.addEventListener(MouseEvent.CLICK, percentPopUp);
  tipAmount_btn.addEventListener(MouseEvent.CLICK, calculateTip);
  share_btn.addEventListener(MouseEvent.CLICK, calculateShare);
  
  function percentPopUp(event:MouseEvent):void /*Tip percentage textbox will be filled with a percentage when a star is clicked on*/
  {
      tipPercent = 0;
      if(event.target.name == "oneStar")
      {
          tipPercent = 5;
      }
      if (event.target.name == "twoStar")
      {
          tipPercent = 10;
      }
      if (event.target.name == "threeStar")
      {
          tipPercent = 20;
      }
      tipPercentage.text = tipPercent + "%";
  
  }
  </code></pre>
