Kirupa Flash / XML gallery - remove next button if there are no more photos

programming flash
1

Hi,
I’m trying to figure out how to remove the 'next_bttn_mc" in the kirupa flash / xml gallery if it there is no photo left to load into the movie (it reaches the end of the images…no more to load)

Also, would like the previous_bttn_mc to be invisible on the first photo.

Thought about trying to do this as an additional node, with one variable = next_bttn_mc _alpha=“0” and another where it equals 100.

Here’s the code, any help would be appreciated:

//#include “galleryActionScript.as”

function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
heading = [];
description = [];
//thumbnails = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
heading* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
//Maybe here? nextBttn* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;

	}
	sload();
	firstImage();
} else {
	content = "file not loaded!";
	
}

}

xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(“autumnwedding.xml”);

Key.addListener(listen);
previous_btn.onRelease = function() {
prevImage();
};
next_btn.onRelease = function() {
nextImage();
};

} 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];
heading_txt.text = heading[p];
picture_num();
}
}
}
function prevImage() {
if (p>0) {
p–;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
