We hired a firm to develop a website in Magento for us. The bulk of the site has custom coding. When users check out either using Credit Card (using PayPal as the merchant service provider) or via PayPal, and they have a RUSH order fee or Tax added on to their order, the checkout is not sending the correct information to PayPal resulting in PayPal rejecting the transaction.
PayPal gateway has rejected request. The totals of the cart item amounts do not match order amounts (#10413: Transaction refused because of an invalid argument. See additional error messages for details)."
The user is given a front end error that says there is an item mismatch.
Our current developer says he cannot fix it. We need this fixed ASAP.
