Hi fellow kirupians.=)

What im trying to is switch bewteen different urls. i have data being pulled in via php file which outputs it as XML and it loads the text and image data. but i want a button to load/switch to a different url for it to load.

[COLOR=#003366]its the “guytees” that i want to swap to “girltees”[/COLOR]

[COLOR=#003366]Any help thanks.[/COLOR]
my code:

var thumb_spacing = 82;
// load variables object to handle loading of text
var myData = new LoadVars();
myData.onData = function(ok) {
 if (ok) {
  title_txt.text = this.title;
  code_txt.text = this.code;
  sizes_txt.text = this.sizes;
  fabric_txt.text = this.fabric;
  fit_txt.text = this.fit;
  price_txt.text = this.price;
  //description_txt.text = raw_text;
 } else {
  trace("Error Loading Data");
 }
};
function GeneratePortfolio(portfolio_xml) {
 var portfolioPictures = portfolio_xml.firstChild.childNodes;
 for (var i = 0; i<portfolioPictures.length; i++) {
  var currentPicture = portfolioPictures*;
  var currentThumb_mc = menu_mc.createEmptyMovieClip("thumbnail_mc"+i, i);
  currentThumb_mc._x = i%3*thumb_spacing;
  currentThumb_mc._y = Math.floor(i/3)*101;
  currentThumb_mc.createEmptyMovieClip("thumb_container", 0);
  currentThumb_mc.thumb_container.loadMovie(currentPicture.attributes.thumb);
  currentThumb_mc.title = currentPicture.attributes.title;
  currentThumb_mc.code = currentPicture.attributes.code;
  currentThumb_mc.image = currentPicture.attributes.image;
  currentThumb_mc.sizes = currentPicture.attributes.sizes;
  currentThumb_mc.fabric = currentPicture.attributes.fabric;
  currentThumb_mc.fit = currentPicture.attributes.fit;
  currentThumb_mc.price = currentPicture.attributes.price;
  /*currentThumb_mc.onRollOver = currentThumb_mc.onDragOver=function () {
  info_txt.text = this.title;
  };
  currentThumb_mc.onRollOut = currentThumb_mc.onDragOut=function () {
  info_txt.text = "";
  };*/
  currentThumb_mc.onRelease = function() {
   image_mc.loadMovie(this.image);
   title_txt.text = this.title.toUpperCase();
   code_txt.text = this.code.toUpperCase();
   sizes_txt.text = this.sizes;
   fabric_txt.text = this.fabric;
   fit_txt.text = this.fit;
   price_txt.text = this.price;
  };
 }
}
// xml object for xml content (defines sources for selections)
var portfolio_xml = new XML();
portfolio_xml.ignoreWhite = true;
portfolio_xml.onLoad = function(success) {
 if (success) {
  GeneratePortfolio(this);
 } else {
  trace("Error loading XML file");
 }
 // no success?  trace error (wont be seen on web)
};
// load

phpfileload = "../apparel.php?prodCategory=guytees";
portfolio_xml.load(phpfileload);
