)

I've tried to:

1. Change servers - server is not the problem.
   
2. Took out &AMT= , then it still didnt work, so i took &PAYMENTREQUEST_0_AMT= out and left &AMT= in... but still didnt work.. now there are both of them.
   

Thanks!

First you are mixing some of the old variables with the new variable's, and you are using some of the same variables both old and new. Here is what your request should be passing over. Once you pass over these variables in this format, your request will go through.

RETURNURL=http://www.mydomainname.com/pp/paypal/process.php
CANCELURL=http://www.mydomainname.com/pp/paypal/cancel_url.php
ALLOWNOTE=1
PAYMENTREQUEST_0_PAYMENTACTION=Sale
PAYMENTREQUEST_0_CURRENCYCODE=EUR
PAYMENTREQUEST_0_AMT=106.72
PAYMENTREQUEST_0_ITEMAMT=106.72

L_PAYMENTREQUEST_0_QTY1=1
L_PAYMENTREQUEST_0_AMT1=21.34
L_PAYMENTREQUEST_0_NAME1=SECONDitem

我们有同样的问题，但我想通了，您需要将Paypal沙箱帐户登录到要测试Paypal付款的PC
