I can’t figure it out…
Basically i am doing an xml external photo gallery and i have 2 buttons(next_btn and prev_btn) and i want the prev button to disappear when the gallery is loaded(because is slide number 1 and there’s no prev images) and do the same at the end of the gallery(no next button because that is the last slide).
This is the code :
var tcount =0
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
thumbnails = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
thumbnails* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
}
firstImage();
thumbnails_fn(tcount);
} else {
content = "file not loaded!";
}
}
preloader.preload_bar._xscale=0
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(“deluxe.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() {
nextImage();
};

picture._x = bgd._x-picture._width/2;

preloader._visible = false;
bgd._width += (picture._width+10-bgd._width)/3;

}
}

this.createEmptyMovieClip(“tscroller”, 1000);

Thanks a lot
