Tutorial Paypal NVP Express Checkout
I'm still learning how to use Express Checkout PayPal with NVP,  
Already read PayPal documentation, but it's to confusing and seems not readable.

Is there any other tutorial out their website which can give detail tutorial and it worked? 
Already tried some website, but their code not working. Already tried PayPal SDK, but the sample code to complicate and not written well.
