Hello all,

I have a portfolio website and found a nice series of code for a slideshow. When I placed in my script I received a 1009 error and have failed to find a fix since it shows no compiler error…

TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at index\_fla::MainTimeline/switchSlide()  
at flash.utils::Timer/\_timerDispatch()  
at flash.utils::Timer/tick()

my line of code…

stop();

//animate in the home\_mc aplha fade, using the Tween class…

//Flash- get code thats going to make the tween work…  
import fl.transitions.Tween;  
import fl.transitions.easing.\*;  
import caurina.transitions.Tweener;

//home\_mc animation - animate in…  
var homeTween:Tween = new Tween(mcSlideHolder, “alpha”, Regular.easeOut, 0, 1, 1, true)  
var columnTween:Tween = new Tween(column\_mc, “alpha”, Regular.easeOut, 0, 1, 1, true);

// delay between slides  
const TIMER\_DELAY:int = 3000;  
// fade time between slides  
const FADE\_TIME:int = 2;

// reference to the current slider container  
var currentContainer:Sprite;  
// index of the current slide  
var intCurrentSlide:int = -1;  
// total slides  
var intSlideCount:int;  
// timer for switching slides  
var slideTimer:Timer;  
// slides holder  
var sprContainer1:Sprite;  
var sprContainer2:Sprite;  
// slides loader  
var slideLoader:Loader;  
// url to slideshow xml  
var strXMLPath:String = “slideshow-data.xml”;  
// slideshow xml loader  
var xmlLoader:URLLoader;  
// slideshow xml  
var xmlSlideshow:XML;

function init():void {  
// create new urlloader for xml file  
xmlLoader = new URLLoader();  
// add listener for complete event  
xmlLoader.addEventListener(Event.COMPLETE, onXMLLoadComplete);  
// load xml file  
xmlLoader.load(new URLRequest(strXMLPath));

```
// create new timer with delay from constant
slideTimer = new Timer(TIMER_DELAY);
// add event listener for timer event
slideTimer.addEventListener(TimerEvent.TIMER, switchSlide);

// create 2 container sprite which will hold the slides and
// add them to the masked movieclip
sprContainer1 = new Sprite();
sprContainer2 = new Sprite();
mcSlideHolder.addChild(sprContainer1);
mcSlideHolder.addChild(sprContainer2);

// keep a reference of the container which is currently
// in the front
currentContainer = sprContainer2;

```

}

function onXMLLoadComplete(e:Event):void {  
// create new xml with the received data  
xmlSlideshow = new XML(e.target.data);  
// get total slide count  
intSlideCount = xmlSlideshow…image.length();  
// switch the first slide without a delay  
switchSlide(null);  
}

function fadeSlideIn(e:Event):void {  
// add loaded slide from slide loader to the  
// current container

```
//-begin fix
try{
currentContainer.removeChildAt(0);
}catch(e:*){}
//-endfix
currentContainer.addChild(slideLoader.content);
// clear preloader text
mcInfo.lbl_loading.text = "";
// fade the current container in and start the slide timer
// when the tween is finished
Tweener.addTween(currentContainer, {alpha:1, time:FADE_TIME, onComplete:function() { slideTimer.start(); }});

```

}

function switchSlide(e:Event):void {  
// check, if the timer is running (needed for the  
// very first switch of the slide)  
if(slideTimer.running)  
slideTimer.stop();

```
// check if we have any slides left and increment
// current slide index
if(intCurrentSlide + 1 &lt; intSlideCount)
	intCurrentSlide++;
// if not, start slideshow from beginning
else
	intCurrentSlide = 0;

// check which container is currently in the front and
// assign currentContainer to the one that's in the back with
// the old slide
if(currentContainer == sprContainer2)
	currentContainer = sprContainer1;
else
	currentContainer = sprContainer2;

// hide the old slide
currentContainer.alpha = 0;
// bring the old slide to the front
mcSlideHolder.swapChildren(sprContainer2, sprContainer1);

// create a new loader for the slide
slideLoader = new Loader();
// add event listener when slide is loaded
slideLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, fadeSlideIn);
// add event listener for the progress

// load the next slide
slideLoader.load(new URLRequest(xmlSlideshow..image[intCurrentSlide].@src));

// show description of the next slide

// show current slide and total slides

```

}

// init slideshow  
init();

Any help would be appreciated!!
