Hi, I've noticed that when I post my requests to the PayPal server, I include the Tax variable with the tax amount generated from my shopping cart, but most of the time, that tax is not calculated into the order total charge that PayPal charges. It did calculate for me once, but the other times, it's like it's not even there. But even when it isn't calculating, the Tax variable is still being handed back to me through the PDT. Anyone else notice this?
