Problem loading vars to flash from php

Hello all,

I have tried repeatedly to sendAndLoad variables from/to flash and php.

The problem actually comes when passing the variables from php to flash, here is the flash code:

var dataOut:LoadVars = new LoadVars();
var dataIn:LoadVars = new LoadVars();

dataOut.username = _level0.usuario.ss.s1; //passing the value of textbox
 dataOut.pass = _level0.contrasena.ss10.s10; //passing the value of textbox

 dataOut.sendAndLoad("http://www.itnmexico.com/Pag%20Pstventa/newlogin.php", dataIn, "POST");

_level0.estatus=“Por favor espere…”; //displaying info to the user

dataIn.onLoad = function() {
if (this.valid==“1”) {
_level0.estatus = ‘Bienvenido’ + this.Name;

import com.greensock.*;
TweenMax.to(_level0.usuario, 1, {_x:1000, _alpha:0});
TweenMax.to(_level0.contrasena, 1, {_x:1000, _alpha:0});
TweenMax.to(_level0.ww, 1, {_x:1000, _alpha:0});

  } 
else {

_level0.estatus = this.retro;
}

}

the php code is the following:

<?php

$usuario=$_POST[‘username’];
$contrasena=$_POST[‘pass’];
$num=1;
if($num==2){
echo 'valid=1&Name= '.$Nombre;
}
else {
echo ‘valid=0&retro=Usuario o contraseña inválidos.’;
}

?>

I have ommited some mysql code, but it would still work this way.

Which is most odd is that when I test the movie in my computer it works perfectly, but when I upload it to the server it doesn’t work anymore.

Please help!!!

Thanks.
