UNPROCESSABLE_ENTITY -- CANNOT_BE_ZERO_OR_NEGATIVE

I'm unable to checkout with any total of goods. My subtotal for this order reads Subtotal: $6.60 and I receive the error message:

Here's the paypal API log with some private information censored:

I'm confused as to why it thinks the order total amount seems to be zero? There are no discounts on the item.

Please advise. Thanks!
