Simple Calculator help

So I found the answer to my problem and here is the code if anyone else needs it;

function calcClick(event:MouseEvent):void

{

          var userNum:Number = Number(userNum.text);

          var total_1:Number = userNum / 400;

          silRes.text = String(total_1);

          var total_2:Number = userNum / 2500;

          finishRes.text = String(total_2);

          var total_3:Number = userNum / 500;

          colorRes.text = String(total_3);

}
