Thanks so much for any help.

I figured out the AS3 for the text imageText.text = xml.image[slideNum].imgTitle;
but I don't know how to write the call for the actual images.
movieclip. '?' = xml.image[slideNum].imgURL;

I went through and added what Chris had done plus I set it up so you did not have to hard code the number of entities like in the example. I also added the code to view the images. In my case I was loading them into a UILoader component. I fixed a couple errors i was getting and it seems to run solid now.

The next thing that would be nice is a play and pause.

//variables
var xmlList:XMLList;
var mcLoader:Loader;

//loads xml and assigns the text field the first
//node using the slideNum variable from above
var xml:XML = new XML();
var loader:URLLoader = new URLLoader();
loader.load(new URLRequest(“images.xml”));
loader.addEventListener(Event.COMPLETE,
function(evt:Event):void {
xml = XML(evt.target.data);
xmlList = xml.children();
trace(xmlList);
var totalSlides:Number = xmlList.length() -1;
var slideNum:Number = 0;
imageFile.source = xml.slide[slideNum].@name.toString();
slideText.text = xml.slide[slideNum].@title.toString();

}
);

//stage event listeners for the movieClip buttons
nextBtn.addEventListener(MouseEvent.CLICK, onClickNextSlide);
prevBtn.addEventListener(MouseEvent.CLICK, onClickPrevSlide);

//this function will change the text depending upon
//which number is fed to the var slideNum in the
//onClickNextSlide function
function changeText(slideNum:Number):void {

imageFile.source = xml.slide[slideNum].@name.toString();
slideText.text = xml.slide[slideNum].@title.toString();
}
changeText(0);

//this function adds 1 to the current number,
//if the current number is 4, it starts over
function onClickNextSlide(event:MouseEvent):void {
//Check var on entering function to keep values within specified range.
if (slideNum >= totalSlides) {
slideNum = 0;
//changeText(0);
}
else {//Increment after check.
slideNum++;
}
trace(slideNum);
trace(totalSlides);
changeText(slideNum);
}

function onClickPrevSlide(event:MouseEvent):void {
//Check var on entering function to keep values withen specified range.
if (slideNum <= 0) {
slideNum = totalSlides +1;
}
//Increment after check.
slideNum–;
trace(slideNum);
trace(totalSlides);
changeText(slideNum);
}

Any ideas why?

Im sure you might have thought about this approch already. The problem was in your itteration functions. You need your dynamic textbox to fill the first value on load for this to work. However do not increment the counter on load.

function onClickNextNews(){
//Check var on entering function to keep values withen specified range.
if (counter >= 4) {
counter = 0;
}
//Increment after check. This is why you need to set initial value. However solves problems later.
counter++;
//Trace when variable is about to be used not when you increment.
trace(counter);
changeText(counter);
}
// this function does the opposite of the one above, it subtracts 1 to current number, when it reaches 0 it starts back at 4 (really only three values are displayed thats the reason for the ending string being the first string also.)
//Same thing here as the next function.
function onClickPrevNews(){
if (counter <= 0) {
counter = 4;
}
counter–;
trace(counter);
changeText(counter);
}
//NOTE: Counter is NumSlide.

Hopefully this helps I like your overall approach by the way. It is cleaner than what I had been using.
