    [L_SEVERITYCODE0] => Error
)

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_AMT0=28.46
L_PAYMENTREQUEST_0_NAME0=FIRSTitem
L_PAYMENTREQUEST_0_NUMBER0=0
L_PAYMENTREQUEST_0_QTY1=1
L_PAYMENTREQUEST_0_AMT1=21.34
L_PAYMENTREQUEST_0_NAME1=SECONDitem
L_PAYMENTREQUEST_0_NUMBER1=1

We have the same problem but i figured it out, you need to login your paypal sandbox account to the pc you are testing your paypal payment
