[PAYPAL]End price from all net prices

[Keenic]

I have PayPal module version 3.1.0 and now the end price with tax is calculating

gross price of product * quantity

and the end price is wrong, e.g. product cost 0,85 € without tax, with tax it is 1,01 € and with 100 pieces the end price in paypal module is 101 € but it should be 101,15 €

When I tried to change $total in setProductsList function i got this message

PayPal response:

TIMESTAMP -> 2012-09-10T10:39:13Z

L_ERRORCODE0 -> 10413

L_SHORTMESSAGE0 -> Transaction refused because of an invalid argument. See additional error messages for details.

L_LONGMESSAGE0 -> The totals of the cart item amounts do not match order amounts.

L_SEVERITYCODE0 -> Error

Is there any chance to change end price with this model:

net price of product * quantity + tax of this product

 

PrestaShop version is 1.4.7.3
