动作脚本小错误

Question

你好，我已经编写了这些代码，当我运行 PUBLISH 时，它没有显示任何错误，但是当我在最后一张海报上运行 flash 窗口时，它显示

TypeError: Error #1010: A term is undefined and has no properties.
    at slider_fla::MainTimeline/nextClick()

这里代码：

    var sliderNum:int = 0;
    var sliderMaxNum:int = 0;

function nextClick(event:MouseEvent):void
{
    if (sliderNum > sliderMaxNum){
        sliderNum = 0;
    }
    var myTween:Tween = new Tween(poster[sliderNum],'x',Strong.easeOut,poster[sliderNum].x,-800,2,true);
    if (sliderNum == sliderMaxNum){
        trace(String(sliderNum));
        trace(String(sliderMaxNum));
        sliderNum = 0;
    } else {
        sliderNum = sliderNum +1;
    }   

    var myTween2:Tween = new Tween(poster[sliderNum],'x',Strong.easeOut,poster[sliderNum].x,(myStage.stageWidth - 640)/2,2,true);
}

我使用此代码加载 XML：

function loadXML(event:Event):void{

    sliderXML=XML(sliderXMLloader.data);
    var xmlDoc:XMLDocument = new XMLDocument();
    xmlDoc.ignoreWhite = true;
    var menuXML:XML = XML(sliderXMLloader.data);
    xmlDoc.parseXML(menuXML.toXMLString());

    //var X:int = 100;

    for each(var listItem:XML in sliderXML..listItem){

             strTitle[sliderMaxNum] = listItem.itemTitle.toString();
             strPosterLink[sliderMaxNum] = listItem.posterLink.toString();
             strVideoLink[sliderMaxNum] = listItem.videoLink.toString();

             var _temp:Loader = new Loader();
             poster.splice(sliderMaxNum, 0, _temp);
             poster[sliderMaxNum].load(new URLRequest(strPosterLink[sliderMaxNum]));
             //var posterClip:MovieClip = new MovieClip();  //load the movieclip
             //posterClip.addChild(poster[sliderMaxNum]);  //convert poster[sliderMaxNum] to movieClip
             addChild(poster[sliderMaxNum]);
             poster[sliderMaxNum].x = myStage.stageWidth;
             poster[sliderMaxNum].y = 28;

             poster[sliderMaxNum].addEventListener(MouseEvent.CLICK, poster_click(sliderMaxNum));

             sliderMaxNum = sliderMaxNum+1;
             }
    LastSliderNum = sliderMaxNum - 1;
    //*************************************************
    var myTween:Tween = new Tween(poster[sliderNum],'x',Strong.easeOut,poster[sliderNum].x,(myStage.stageWidth - 640)/2,2,true);
    //*************************************************

这是完整的代码：

我只是将其最小化，只留下我认为可能有问题的代码
