I have eight INFO buttons that once you click pulls up a popup/Movie clip with a picture, title, and description being pulled from an xml file. My next button doesn't seem to work either.

I want to be able to tell which xml nodes to pull based on which INFO button is pressed.

sample work: http://www.smooth-ness.com/flash.html

Select "Terrace Options" Then at the bottom the "INFO" button. There will be an info button by all items listed.
function loadXML(loaded) {
 
if (loaded) {
 
xmlNode = this.firstChild;
image = [];
titlehere = [];
description = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
 
image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
titlehere[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
description[i] = xmlNode.childNodes[i].childNodes[2].firstChild.nodeValue;
 
}
firstImage();
 
} else {
 
content = "file not loaded!";
 
}
 
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
/////////////////////////////////////
listen = new Object();
listen.onKeyDown = function() {
 
if (Key.getCode() == Key.LEFT) {
 
prevImage();
 
} else if (Key.getCode() == Key.RIGHT) {
 
nextImage();
 
}
 
};
Key.addListener(listen);
previous_btn.onRelease = function() {
 
prevImage();
 
};
next_btn.onRelease = function() {
trace(clicked);
nextImage();
 
};
/////////////////////////////////////
p = 0;
this.onEnterFrame = function() {
 
filesize = picture.getBytesTotal();
loaded = picture.getBytesLoaded();
preloader._visible = true;
if (loaded != filesize) {
 
preloader.preload_bar._xscale = 100*loaded/filesize;
 
} else {
 
preloader._visible = false;
if (picture._alpha<100) {
 
picture._alpha += 10;
 
}
 
}
 
};
function nextImage() {
 
if (p<(total-1)) {
 
p++;
if (loaded == filesize) {
 
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
title_txt.text = titlehere[p];
 
picture_num();
 
}
 
}
 
}
function prevImage() {
 
if (p>0) {
 
p--;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
title_txt.text = titlehere[p];
 
picture_num();
 
}
 
}
function firstImage() {
 
if (loaded == filesize) {
 
picture._alpha = 0;
picture.loadMovie(image[0], 1);
desc_txt.text = description[0];
title_txt.text = titlehere[1];
picture_num();
 
}
 
}
function picture_num() {
 
current_pos = p+1;
pos_txt.text = current_pos+" / "+total;
 
}

your code seems to be assuming a normal increment, i'm assuming this is not the case. as the user may not press them in order.
so you don't really want a next / back options rather just click and activate.

so easiest way it to give your buttons names like btn1 btn2 etc. then pull the number from that button name you can use substring (check help file) - then parse that into your arrays (-1 if you're using 1 index) instead of using that p counter.

ie.


btn1.onRelease = function() {
	var num:Number = this._name.substr(3,1);
	trace(num);
	doImage(num);
}
 
function doImage(which:Number) {
	//assuming you're using 1 index.
	var num:Number = which - 1;
	picture.loadMovie(image[num], 1);
	desct_txt.text = description[num];
}
