AS3/ XML errors with a slideshow... Anyone know why?

1

Building a slideshow gallery with xml, but alas I am stuck…
With this code and a UILoader component, I keep getting these screwy errors:

TypeError: Error #1034: Type Coercion failed: cannot convert true to flash.display.MovieClip.
at MyTicketShow_fla::MainTimeline/onComplete()

stop();
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
import gs.*;

var slidesX:XML;
var picList:XMLList;
var currentPic:Number = 0;
var loader:URLLoader = new URLLoader();
var timeline:TimelineLite = new TimelineLite();

loader.addEventListener(Event.COMPLETE, onComplete);
loader.load(new URLRequest("slideshow.xml"));

function onComplete(e:Event):void {
    slidesX = new XML(loader.data);
    picList = slidesX.img;
    updatePic(currentPic);
    txtBox_mc.getTix = true;
    txtBox_mc.next_btn = true;
    txtBox_mc.prev_btn = true;
    txtBox_mc.next_btn.addEventListener(MouseEvent.CLICK, nextPic);
    txtBox_mc.prev_btn.addEventListener(MouseEvent.CLICK, prevPic);
}

function nextPic(e:MouseEvent):void {
    if (currentPic < picList.length() - 1) {
        currentPic++;
    } else {
        currentPic = 0;
    }
    updatePic(currentPic);
}

function prevPic(e:MouseEvent):void {
    if (currentPic == 0) {
        currentPic = picList.length() - 1;
    } else {
        currentPic--;
    }
    updatePic(currentPic);
}

function updatePic(index:Number):void {
    picLoader.source = picList[index].img;
    txtBox_mc.Shower.htmlText = picList[index].shower;
    txtBox_mc.Dater.htmlText = picList[index].dater;
    txtBox_mc.Placer.htmlText = picList[index].placer;

}

txtBox_mc.x = 0;
txtBox_mc.y = 290;
timeline.insert(new TweenLite(txtBox_mc, .5, {y:190, ease:Back.easeOut}), 0);

frustration is setting in…

Thanks for all the help!
