PayFlow - Shipping Only Bug

• https://mail.google.com/mail/u/0/#inbox/15e3f2dc2c5d697c

I feel like we've addressed in this in the past, but have a fresh report of this problem happening on our latest release.

They're trying to sell a product that is free but the buyer has to pay for shipping, so shipping is the only charge on the order. The user says that with Express Checkout things work fine, but with PayFlow it's still not working. Here is a sample PayFlow request that failed.

We can see that FREIGHTAMT was included in the request along with AMT. When a value for FREIGHTAMT is passed, though, the PayPal system requires that we also include other line item details, tax, handling, etc. So, on orders where shipping is the only thing being charged we need to leave FREIGHTAMT out and just use AMT by itself.
