Actionscript 3 在actionscript中连接不显示符号

我有一个flash程序，它应该根据你给账单的评级来计算账单的小费。在我的小费百分比框中，我试图将其连接起来以显示相应的值+百分比符号，但百分比符号没有显示出来；只有价值存在。下面是代码

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 + "%";

}
