10413 Transaction refused because of an invalid argument

[Billyboy]

This is happening to me also.

I have my Shipping Charges (postage) set to the Flat rate ... if that helps solve the problem.

I went to this thread, but it seems to be unresolved

Would appreciate some help on this,

thx guys

The problem occurs as a result of trying to add up all the charges on the line-item details of the order, including products, attributes, shipping, coupons, and taxes, in conjunction with all the tax rates and shipping rules configured in your store as well as the taxation mode (tax-included in pricing vs not), etc.

Without all those exact details and debug logs from failed transactions, it's impossible to help you.

I dont know what I did, but it seems to be working now. Thx

This comes from a code bug in the PayPal module. I'm using a one line fix:

/includes/modules/payment/paypalwpp.php
add this on line 534:

// LS PATCH - remove commas so number_format doesn't screw up values over 1000
$options['AMT'] = str_replace(',', '', $options['AMT']);

so it looks like this:

// LS PATCH - remove commas so number_format doesn't screw up values over 1000
$options['AMT'] = str_replace(',', '', $options['AMT']);

      $response = $doPayPal->DoExpressCheckoutPayment($_SESSION['paypal_ec_token'],
                                                      $_SESSION['paypal_ec_payer_id'],
                                                      number_format((isset($options['AMT']) ? $options['AMT'] : $order_amount), 2),
                                                      $options);

I got the same error on my store so I am trying the fix posted by lsenft

[stagebrace]

The PayPal API allows for a comma.

I am also having this problem. A customer is getting a little frustrated as she is trying to order 3 items and says The cost continues to show a total of $0.00. paypal notified me and it says....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.

Attn: DrByte, I updated paypalwpp.php to include your changes listed in your link (which I notice the thread has been closed on hence I am posting here) and this partially fixed my issue (Thank you!)

Unfortunately it only fixed the 10413 error for transactions that include a coupon. If no coupon is used I still get the 10413 error.

Hope you are not too over this topic as I would really appreciate your thoughts (and would be happy to send link to log files if it would tempt you to look into it again).

Further...if I turn tax and shipping off in order totals module, it works fine...Paypal that is. Unfortunately this means my coupon customers are not charged shipping or tax though.

So if I remove tax and shipping from coupon it will probably work...ah gees, sorry, hope I can delete this
