Hi,

I have this code of parallel payment using express checkout :

index.php

<?php
require 'paypal.php';

$total = 0.1;
$mail_1 = "first_email";
$mail_2 = "second-email";
$paypal = "#";
$paypal = new Paypal();
$params = array(
	'RETURNURL' => 'http://site.com/process.php',
	'CANCELURL' => 'http://site.com/cancel.php',
    'NOSHIPPING' => '1',
	'LOGOIMG' => '', // 190 60 PNG JPG
	'LANDINGPAGE' => 'Billing', // OR Login
	'BRANDNAME' => 'MUSTAPHA',
	'SOLUTIONTYPE' => 'SOLE',
	
	'PAYMENTREQUEST_0_AMT' => $total,
	'PAYMENTREQUEST_0_CURRENCYCODE' => 'EUR',
	'PAYMENTREQUEST_0_ITEMAMT' => $total,
	'PAYMENTREQUEST_0_DESC' => 'description detaillé',
	'PAYMENTREQUEST_0_SELLERPAYPALACCOUNTID' => $mail_1,
	'PAYMENTREQUEST_0_PAYMENTREQUESTID' => '1234567',
	'PAYMENTREQUEST_0_PAYMENTACTION' => 'Order',
	
	'PAYMENTREQUEST_1_AMT' => $total,
	'PAYMENTREQUEST_1_CURRENCYCODE' => 'EUR',
	'PAYMENTREQUEST_1_ITEMAMT' => $total,
	'PAYMENTREQUEST_1_DESC' => ' description detaillé222',
	'PAYMENTREQUEST_1_SELLERPAYPALACCOUNTID' => $mail_2,
	'PAYMENTREQUEST_1_PAYMENTREQUESTID' => '1234567222',
	'PAYMENTREQUEST_1_PAYMENTACTION' => 'Order',
	
);

$response = $paypal->request('SetExpressCheckout', $params);
if($response){
	$paypal = 'https://www.paypal.com/webscr?cmd=_express-checkout&useraction=commit&token=' . $response['TOKEN'];
}else{
	var_dump($paypal->errors);
	die('Erreur ');
}

}

1) details (email0 and 1, desc 0 and 1, Amount 0 and 1) not display in page payment paypal

2) doesn't work correctly: when I test live and click to pay, the redirection is to return URL, but when I check my paypal account there is no transation done?

What did I do wrong??
