Xml guestbook with phph problem

EDIT: Well, I went with a guestbook of flashkit and edited it to my needs, I don’t need help anymore.

Hi there. Well, I did the tutorial for the guestbook, tho I tried to change it so it would just be on one window, instead of opening a new one up for the enter message thing. It writes to the xml file, but doesn’t show up in the myGuestbook text field. You can see it at www.g3cko.com/concept.html and then click on guestbook. My edited actionscript is as follows

var currPage = 0;
var showAmount = 10; // set this to the amount of entries you want to view at a time
previous._visible = false;
createMessage._visible = true;
createButton.onRelease = function(){

this._visible = false;
this._parent.createMessage._visible = true;
if (createMessage.nameField.text == ""){

Selection.setFocus(createMessage.nameField);

}
else if (createMessage.messageField.text == ""){

Selection.setFocus(createMessage.messageField);

}

}
 
// **** Load XML ****************************
myXML = new XML();
myXML.ignoreWhite = true;
receiverXML = new XML();
 
myXML.onLoad = function(success){

myXML.contentType = "text/xml";
if (success){

this.showXML();

}
else{

trace("Error loading XML file");

}

}
myIdentifier=Math.round(Math.random()*10000);
myXML.load("guestbook.xml?uniq="+myIdentifier);
 
receiverXML.onLoad = function(){

this.contentType = "text/xml";
_root.currPage = 0;
this.showXML();

}

createMessage.sendButton.onRelease = function(){

var myName = this._parent.nameField.text;
var myMessage = this._parent.messageField.text;
if (myName == ""){

this._parent.errorField.text = "please fill out your name";
Selection.setFocus(this._parent.nameField);

}
else if (myMessage == ""){

this._parent.errorField.text = "please leave a message";
Selection.setFocus(this._parent.messageField);

}
else {

myXML.firstChild.appendChild(myXML.createElement("entry"));
myXML.firstChild.lastChild.attributes.myName = myName;
myXML.firstChild.lastChild.appendChild(myXML.createElement("myText"));
myXML.firstChild.lastChild.lastChild.appendChild(myXML.createTextNode(myMessage));
myXML.sendAndLoad("processXML.php", receiverXML);

}

}
XML.prototype.showXML = function(){

myGuestbook.scroll = 1;
myGuestbook.htmlText = "";
var numItems = this.firstChild.childNodes.length;
var firstItem = numItems - (currPage*showAmount);
if (currPage == 0) previous._visible = false;
var lastItem = firstItem - showAmount ;
if (lastItem<=0) {

lastItem = 0;
next._visible = false;

}

if (firstItem == lastItem+1) nowShowing.text = "Showing message " + firstItem;
else nowShowing.text = "Showing message " + firstItem + " to " + (lastItem + 1);
for (i=(firstItem-1); i>= lastItem; i--){

myGuestbook.htmlText += "<B>" + this.firstChild.childNodes*.attributes.myName + "</B> wrote:
";
myGuestbook.htmlText += this.firstChild.childNodes*.firstChild.firstChild.nodeValue + "

";

}

}
previous.onRelease = function(){

currPage--;
myXML.showXML();
next._visible = true;

}
next.onRelease = function(){

currPage++;
myXML.showXML();
previous._visible = true;

}
