How do I resolve a file upload error code 2?

<form enctype="multipart/form-data" action="eje02.php" method="post">

 <input type="hidden" name="MAX_FILE_SIZE" value="2000000"/> 


Send this file: <input name="userfile" type="file"  value="" />
<input type="submit" value="Send File">
</form>

The PHP file:

if(  is_uploaded_file(  $_FILES['userfile']['tmp_name'])   ){
    print "<h1> Archivo subido!</h1>"; 

}else{
    /** Hubo un error */
    $codigo_de_error= $_FILES['userfile']['error'];
    $mensaje="";

    switch(  $codigo_de_error){
    case UPLOAD_ERR_OK: //valor 0
        $mensaje="Archivo subido correctamente";
        break;
    case UPLOAD_ERR_INI_SIZE:
        $mensaje="El fichero subido excede la directiva upload_max_size de php.ini";
        break;
    case UPLOAD_ERR_FORM_SIZE:
        $tama= ( (int)$_FILES['userfile']['size']  )/1024;

        $mensaje="El fichero subido excede la directiva MAX_FILE_SIZE especificada 
        en el formulario,  Size del archivo es $tama";
        break;
    case UPLOAD_ERR_PARTIAL:
        $mensaje="Archivo parcialmente subido";
        break;
    case UPLOAD_ERR_NO_FILE:
        $mensaje="No se subio ningun fichero";
        break;
    case UPLOAD_ERR_NO_TMP_DIR:
        $mensaje="Falta la carpeta temporal. ( desde php 5.0.3)";
        break;
    case UPLOAD_ERR_CANT_WRITE:
        $mensaje="No se pudo escribir el fichero en el disco (desde php 5.1.0)";
        break;
        case UPLOAD_ERR_EXTENSION:
        $mensaje="Una extension de PHP detuvo la subida del fichero (desde php 5.2.0)";
        break;
    }
    print "Codigo {$_FILES['userfile']['error']}  ,  $mensaje";
}

I just want to upload the file and no more, but I have seen in the php.ini that the maximum upload size is 2M, so I have put 2000000 for the MAX_FILE_SIZE, and still generates the error 2. Any suggestions?

A close to the server, I'm using xamp
