Help converting verical to horizontal format menu

Hi
I have this action script where I need help to change into a horizontal menu format. Can someone please help. Script was from kirupa forum and it is called ‘flashnav’ and it reads ‘images.xml’ . Its a great script but only if it couild me converted to display horizontally.

Thanks in advance

MovieClip.prototype.easeY = function(y){
this.onEnterFrame = function(){
this._y = y-(y-this._y)/1.2;
if(Math.abs(y-this._y) <= 1){
delete this.onEnterFrame;
this._y = y;
}
}
}

images = new Array();
xml_file = “images.xml”;

xml = new XML();
xml.ignoreWhite = true;
xml.onLoad = function(ok){
if(ok){
count = this.firstChild.childNodes.length;
for(var i=0;i<count;i++){
curNode = this.firstChild.childNodes*;
images* = {path:curNode.firstChild.firstChild.nodeValue}
}
boot();
} else {
trace(“Could not load “+xml_file+”.”);
}
}
xml.load(xml_file);

// ------------------------------------------------------------

spacing = 5;
boot = function(){
for(var i=0;i<images.length;i++){
mc = container.attachMovie(“thumbMC”,“thumb”+i,i);
loader = mc.loader;
aux = mc.aux;
mc._y = i*(55+spacing);
mc.loader.loadMovie(images*.path);
mc.aux.onEnterFrame = function(){
if(this._parent.loader._width > 0){
delete this.onEnterFrame;
this._parent.onRelease = function(){

            }
        }
    }
}
setRollOver();

}
setRollOver = function(){
this.onEnterFrame = function(){
if(this.mask.hitTest(_root._xmouse,_root._ymouse)){
slideMenu();
}
}
}
slideMenu = function(){
diffspacing = 20;
diff = this._parent._ymouse - (this._y+diffspacing);
scale = diff100/(this.mask._height-2diffspacing); // once to compensate, another to add
scale = Math.max(0,Math.min(100,scale)); // confine within 0->100
target = -scale*(this.container._height-this.mask._height)/100;
this.container.easeY(target);
}
