Flash 8 login showing strange behaviour

Question

I am developing a Flash 8 login for my website but the
problem is once loaded I fill in my credentials and press login....
It only recieves the password and not the username (alert box
used to show this) and once first attempt is over I try again and
nothing is alerted - something to do with caching?
Anyway here is the actionscript 2 that I believe is causing
the problem:
import flash.external.ExternalInterface;
var callJS = new Object();
btn_ok.addEventListener("click",callJS);
callJS.click = function(evt: Object)
//create a new LoadVars object
myvars = new LoadVars();
//set variables in the object
myvars.user = txt_login.text;
myvars.pass = txt_password.text;
ExternalInterface.call("Login", user, pass);
Thanks anyone

Of course oops.
Well this is my latest attempt with the help of a tutorial
(tutorial not using AJAX though, PHP):
import flash.external.ExternalInterface;
btn_ok.onRelease = function()
var myLogin:String = txt_login.text ;
var myPassword:String = txt_password.text ;
maVariable = new LoadVars();
maVariable.var_login = myLogin ;
maVariable.var_password = myPassword;
maVariable.onLoad = function()
if ( maVariable.allow == 1)
getURL("index.php");
else
txt_result.text = "Login/Password incorrect";
ExternalInterface.call("Login", maVariable)
This gives a weird error i.e. it refers to code I did not
know existed. Anyway this is wrong as the AJAX will have to recieve
two variables (username and password) not one (maVariable). Or
maybe AJAX can split the maVariable and then use it?
