stop();
loginError.visible = false;
var loginXml:XML;
var loader:URLLoader = new URLLoader(); 
loader.load(new URLRequest("logindata.xml"));
loader.addEventListener(Event.COMPLETE, loadXML);
var loginData = new Array();
var temp:Array = new Array();
function loadXML(e:Event):void
{
    loginXml = new XML(e.target.data);
	var total = loginXml.item.length();
	var x:int = 0;
	for(x=0; x < total; x++)
	{
		loginData[x] = new Array();
		loginData[x][0] = loginXml.item[x].user.toString();
		loginData[x][1] = loginXml.item[x].pass.toString();
	}
 
}
loginBtn.addEventListener(MouseEvent.CLICK, loginFunction2);
 
function loginFunction2(e:MouseEvent):void
{
	var success:Boolean = false;
    //SEEMS TO BE WHERE MY ERROR STARTS

I'd just make a global variable

var loginXml:XML;
var loader:URLLoader = new URLLoader(); 
loader.load(new URLRequest("logindata.xml"));
loader.addEventListener(Event.COMPLETE, loadXML);
var loginData = new Array();
var temp:Array = new Array();


var gtotal:int = 0;

function loadXML(e:Event):void
{
    loginXml = new XML(e.target.data);
	gtotal = loginXml.item.length();	
                var x:int = 0;
	for(x=0; x < gtotal; x++)
	{
		loginData[x] = new Array();
		loginData[x][0] = loginXml.item[x].user.toString();
		loginData[x][1] = loginXml.item[x].pass.toString();
		
		//trace it out
		//trace(loginData[x][1]);
		
		
	}
	
	//trace(gtotal);
	
}

button1.addEventListener(MouseEvent.CLICK, go);
function go(e:MouseEvent)
{
  var success:Boolean = false;

   
	for(var i=0; i < gtotal; i++)                   //Most Likley the Error
	{
		if(user.text == loginData[i][0] && pass.text == loginData[i][1])
		  {
			  success = true;
			  //gotoAndStop(user.text);
		  }
	}
	if(!success)
	{
		//loginError.visible = true;
	}
	
	trace(success);

}

my xml file:

In AS 3.0, its very simple to find the length.

Step 1:

Use this:

 Help with Code Tags 
 Graphics and Multimedia Syntax (Toggle Plain Text) 
var loginform:XMLList;
var total:Number=0;
var loginform:XMLList;
var total:Number=0;

instead of :

 Help with Code Tags 
 Graphics and Multimedia Syntax (Toggle Plain Text) 
var gtotal:int = 0;
var gtotal:int = 0;

Step 2:

use this:

 Help with Code Tags 
 Graphics and Multimedia Syntax (Toggle Plain Text) 
total = loginform.length();
total = loginform.length();

instead of:

 Help with Code Tags 
 Graphics and Multimedia Syntax (Toggle Plain Text) 
gtotal = loginXml.item.length();
gtotal = loginXml.item.length();

Sure It will work, if yes, mark as solved. Thanks

I looked into your code and executed the half, but your method of total is perfectly working.

Mr. DevC++4.9.9.2,

I am so sorry I am confused forget all those things said above, that is also correct, but in your program nothing is wrong except you have to remove two parenthesis in length function, thats it done.

var lengthLD:int = loginData.length;

Thanks & Regards,

Yep post #5 was the correct answer, or should I say the shortest answer/fix.
