Fading photogallery does not work

Hello,

In the photogallery that I have, the button 12 and 13 don’t work. It does not load image 12 and 13. I :{ have spend a lot of time to debug it but I do not see why it does not work.

You can download the Flash file from www.parkstkdacademy.com/gallery-loader.zip

Basically, each button has the actionscript below:
-For image 1 -> on(rollOver) {
controller.setActive(1);}
-For image 2 -> on(rollOver) {
controller.setActive(1);}

-For image 13 -> on(rollOver) {
controller.setActive(13);}

This is the main actionscript:
onClipEvent(load) {

// anti-irritation measure
fscommand("allowscale","false");

// set the number of images you're using
// (they should be named image1, image2, etc)
var numImages = 13;

// set the default image
var defaultImage = Math.floor(1+Math.random()*numImages);

// fading speed; 0 is forever, 1 is immediate
var fadeSpeed = 0.20;

// the timer lets us stop the procedure after a certain number of frames 
var timer=0;

// Do some initial setting-up to each image
var images = new Array();
for (var i=0; i<numImages; i++) {

	// it's quicker if we reference them all from an array
	images* = _root["image"+(i+1)];

	// make all alphas 0 initially
	images*._alpha = 0;

	// set a variable called 'targetAlpha' in each
	images*.targetAlpha = 0;
}

// function to set the active image
function setActive(image) {

	// set the target alpha of the active image to 100,
	// and the target alphas of the others to 0.
	for (var i=0; i<numImages; i++) {
		if (i+1 == image) {
			images*.targetAlpha = 100;
		} else {
			images*.targetAlpha = 0;
		}
	}

	// turn on the enterFrame function
	doStuff=eF;

	// reset timer
	timer=0;
}

// this will happen every frame the movie is active
function ef() {

	// for each image
	for (var i=0; i<numImages; i++) {

		// move the alpha of the image closer to that image's target alpha
		images*._alpha += (images*.targetAlpha - images*._alpha) * fadeSpeed;		
	}

	// if it's been active for >30 frames, stop the enterFrame behaviour
	if (timer++ > 30) {
		doStuff = null;
	}
}

// start with the default image
setActive(defaultImage);

}

onClipEvent(enterFrame) {

doStuff();

}

Thank you very much for helping me out.
