Flash MX2004 Slide Presentation back/forward

[bllgnn]

Can someone please point me to some documentation regarding how to get the next or previous slide to show? I have tried using a Template (Tech Slide Presentation), but if I insert a nested screen, it does not show its parent.

I want to create a slide show showing how something is built, slide by slide. So, each slide is a nested screen of the one before it, adding more to what was there before. But when I test it, using the buttons from the template, it skips from the presentation slide to the last great-great-great grandchild.

Any help will be appreciated.

Here is the ActionScript from the Template: Tech Slide Presentation.

Would someone kindly give me a rough translation in everyday words as to what is happening here in this code?

Maybe then I can figure out how to play many slides with one child in many generations one after the other.

btn,next,<forwardBtn>
on (release) {

// Locate the screen holding the anchor for this behavior
var screen = null;
var target = this;
while((screen == null) && (target != undefined) && (target != null))
{
if(target instanceof mx.screens.Screen)
{
screen = target;
}
else
{
target = target._parent;
}
}

// If there's a Slide to apply the behavior to, then do so
if(screen instanceof mx.screens.Slide)
{
screen.rootSlide.currentSlide.gotoNextSlide();
}


}
on (keyPress "<Down>") {

// Locate the screen that is the target of the behavior
var screen = null;
var target = this;
while((screen == null) && (target != undefined) && (target != null))
{
if(target instanceof mx.screens.Screen)
{
screen = target;
}
else
{
target = target._parent;
}
}

// If there's a Slide to apply the behavior to, then do so
if(screen instanceof mx.screens.Slide)
{
screen.rootSlide.gotoLastSlide();
}

}

I'm really looking forward to understanding this!

Thanks,

Bill

Never mind. I figured it out by trial and error.

An undocumented feature is that with a parent and child relationship, only the child will appear. A parent never appears. So, to show the incremental steps, a parent (Step1) has to have two children: one identical to the parent (Step1A) and another with the additional information (Step2). Step2 has two kids: Step2A and Step3 and so on.
