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

The PayPal API allows for a comma.

A more correct fix to lsenft's suggestion is posted here: http://www.zen-cart.com/forum/showthread.php?p=786569#post786569

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

Hello,

I have using paypal payment pro. My store default currency is HKD. When i use this currency and make purchase 10413 Transaction refused error displayed. I have also enable the debug in paypal. this is paypal error log

Please help to fix this problem.

Thanks in advance

Hello,
I have fixed the problem. the problem is in currency setup. we should setup the USD value is 1.0000. The currency values only based on USD and we can set any thing currency as default currency. Now the paypal works fine.
Thanks.

I am currently having this problem and have spent nearly two days reading forum threads and trying fixes.

I have made the change as suggested by Dr Byte which in his own words is "A workaround which has produced **moderate **success is this:"

http://www.zen-cart.com/forum/showthread.php?p=786569#post786569

Unfortunetly for me moderate won't keep me in a job!

Does anybody have an absolute definite answer to this problem? And if so rather than pointing me to a 12 page discussion on another yet thread on this topic can you please just post the final solution here??

Zen Cart v1.3.8a/v1.3.8

I am seeing negative values in the payment logs as per below, whether this is alarming or not i don't know.

Details:Array
(
[ITEMAMT] => 16
[HANDLINGAMT] => -2.09
[SHIPPINGAMT] => 0
[TAXAMT] => 2.09
[AMT] => 16
)

I can supply full logs on request.

The RED X, or the definitive answer? Sorry but several questions need to be answered first.
Does the issue occur with a base install of Zen Cart, or an add on, or your hosts setup, other..

You may need to perform several experimental installs to be able to turn the problem on and off.

Hi everyone,

Just thought I'd weigh in on this topic, in my first post and all.

I've been trying to sort out this issue for about a week, and just like many others it seemed to happen for no explanation. Anyway, I applied a couple of the patches that have been submitted and none seemed to work, but I think I finally found what was causing the problem for me, and hopefully a few other people might find this helpful.

Though in hindsight it seems like a "duh" moment, what I found was I had my settings in Localisation > Currencies set to USD as default when I'm actually using AUD, but I had Modules > Payment > PPEC > Transaction Currency set to "only AUD", so PayPal was multiplying the value by the old exchange rate after the checkout. So I changed the default to AUD and set the exchange rate to 1.000, and that's fixed it for me.

The reason it never occurred to me before is that somehow I'd already had a number of transactions go through without problems. It was a simple oversight, but I may not be the only new Zenner who missed it.

Cheers,

Matt

Hi there I'm having a problem with error 10413 too.

Here's my situation: Have a 50% off sale on at the moment, credit card transactions are working fine but Paypal Express isn't

An originally priced $35 item is purchased and best way shipping is set to a flat $8. These prices include a 10% GST so pretax prices entered into Zencart are $31.82 and $7.27. Final cost after discount should be $25.50 inc GST ($35 discounted to $17.50 plus $8 shipping).

Paypal debugging shows:

[ITEMAMT] => 17.50
[HANDLINGAMT] => 2.32
[SHIPPINGAMT] => 8.80
[TAXAMT] => 1.52
[AMT] => 25.50

Error returned is "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."

The shipping amount of $8.80 seems to indicate that the GST is being applied twice? This doesn't occur for credit card transactions.

How can i fix this? Any help much appreciated!
