[F8] Random retrieved from POST

[Pinkmischief]

Hi guys i have this flash form which simply sends a inputted username and password to a PHP page which tests only if the username exists at the moment in the database and then the PHP sends a response back to flash to say either yes or no and then flash puts it in the errormsg display.

Now what i am experiencing is that the PHP page that pops up always says &login=YES& when i put in the right username but flash sometimes gets a yes but sometimes gets a &login=NO& and even sometimes a undefined :S when nothing has changed ??

Please ignore the Age Dropdown on the form i keep meaning to remove it so it has no bearing on the POST.

The white textarea that displays some traced out var information on the right hand side i hope will be useful to someone inhelping me resolve this....

Username on form is Admin password can be anything as the PHP only checks for the username at the moment.

Sorry for the long post guys but im at my wits end with this......

ActionScript here :

	stop();
	///PHP PROCESSING LOGIN PAGE ADDRESS
	var WebAddress:String ="http://localhost/flash/functions/login.php";
	//Result var contains the retrieved info from PHP file.
	//var Result = new LoadVars(); 
	var Age:Number
	var Username:String
	var Userpassword:String

for(var i:Number = 1; i<100; i++){
	age.addItem(i);
}
	

myBtn_btn.onRelease = function() {
	 Age = age.selectedIndex+1;
	 Username = username.text;
	 Userpassword = userpass.text;
	trace("You are "+Age+" years old and Your username is "+Username+ " And your password is " +Userpassword);
 	//Open page to display the information using GET because testing in the development.
	getURL(WebAddress,"_blank","POST");
			////////COPY/PASTEMODIFICATION FROM WEBSITE TEST CODE///////////

					// here is a reference to this timeline
var here = this
// create an object to store the variables
varReceiver = new LoadVars();
// load a file
varReceiver.load("http://localhost/flash/functions/login.php");
// when the variables finish loading
//trigger something
varReceiver.onLoad = function() {
		
	// show some text in a text field
	// using the loaded variables
	//here.createTextField("t_txt", 1, 100, 100, 1, 1);
	//here.t_txt.autoSize = true;
	
	//here.t_txt.text = "My first name is " + this.fName + ".\n";
	//here.t_txt.text += "My last name is " + this.lName + ".\n";
	//here.t_txt.text += "I'm " + this.age + " years old.";
	errormsg.text = this.login;
	//trace(VarReceiver);
	myTrace.text = varReceiver;
	};

			////////////END TEST CODE///////////////
                        /////MY HAND CODED FUNCTION WHICH I COULD NOT GET TO WORK////
			//Result.onLoad = function (success){
			//if(success){
				//trace("Result : "+this.Result);
				//trace("Variables Loaded");
				//errormsg.text += Result;
			//}else{
				//trace("Error loading page");
			//}
	///}
	///Result.load(WebAddress);
}

The PHP code :

$login ="";
$Username = ucfirst($_POST['Username']);
$Userpassword = md5($_POST['Userpassword']);

//Search for user in DB 
$sql = ("SELECT * FROM `users` WHERE `Username` = '".$Username."'");
$query = mysql_query($sql);
    $result = mysql_fetch_array($query);
    if($result == ""){
        $login = "NO";
        echo $result;
        }else{
        //write back to flash YES user is registered
        $login = "YES";
        ///////
        } 

Please can someone help me with this its almost 2 days of trying to get a simple send and receive from Flash/PHP going , I am considering of giving up on Flash completely.... As even the most simplest of tasks seems like a impossible task.....

Many many thanks for those of you who take the time out to read and respond to this epic post.
