What's happening is that I can successfully login paypal and I can see buyer's name, address and the correct price from the application there, but when I redirect to review.php, it will not show any value such as Name, Email, and Your payment on the page. It seems that GetExpressCheckoutDetails is not working and I wonder if I have missed some settings somewhere on the line.
Could anyone please help me out?
I've modified followings. (I've not made any modification on review.php)
