Just had a customer come up against an error: "Error: There was an error processing your payment: (10413 Transaction refused because of an invalid argument. See additional error messages for details.) The totals of the cart item amounts do not match order amounts. "
This is a paypal error code, which gives further information "If you get this error, be sure the total of the payment detail item parameters, such as ItemTotal, HandlingTotal, TaxTotal, and so forth add up to the the order total."
This seems to me like it must be a bug either at foxycart or paypal, not with our store configuration. That is, either we're sending the wrong item amounts to paypal, or they aren't adding correctly. Thoughts?
