[RESOLVED] Tutorial Code Not Working

I really hate when you read a tutorial from some "expert" and what it tells you to do is wrong.

I was doing a tutorial for a XML slide show, and the last line of code doesn't work quite right:

function timerListener (e:TimerEvent):void{

my_playback_counter++;
if (my_playback_counter == my_total){
my_playback_counter =0;
}
nextImage();

}

For some reason that only sends the my_playback_counter to 1. And it just sits there twitching. So when I tried to change the tutorial code to:

function timerListener (e:TimerEvent):void{

if (my_playback_counter <= my_total){
my_playback_counter++;
}
else {
my_playback_counter = 0;
}
nextImage();

}

It plays through to the last image, and then I get this Output message:

TypeError: Error #2007: Parameter child must be non-null.

at slideShowXML_fla::MainTimeline/nextImage()
at slideShowXML_fla::MainTimeline/timerListener()

Sometimes I just hate programming...

Thanks in advance

It's difficult to discern your problem from the information you have provided. I can tell you that your problem , at least with your adjusted code , is originating from the nextImage method. Something is trying to be added as a child to a display object that does not exist. As for the original issue , i dont really know where to begin. Have you tried tracing out values for my_playback_counter , my_total ? How is this tutorial being used ? I can see that your code is just on the timeline somewhere , that might be part of the problem.

Thanks AttackRabbit (cool name BTW),

I don't have the code right in front of me tonight, I'll check it out tomorrow, and see if I can get it to work right.

I don't know exactly what I did wrong, and I don't know what I did to fix it, but for some reason I got it working :)
