Transaction refused becaused invalid argument

[dcmall]

Hi,

I have recently configured the PayPal express in my shopping cart.

The outlook of the store looks so nice and cool with this Paypal express options.

When diverted to the paypal website for the processing of payment, there isn't any option for me not to sign up as Paypal member, although I have set the Paypal Account Option to ON. No matter what I have tried, still the same outcome and thus I accepted the fate. Afterall, most importantly, is that the transaction can go through.

However, when I complete the transaction at paypal website and return to my shopping cart, the following message appears:

"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."

Looked through the log file but could not identified what went wrong. (Frankly speaking, I know nuts in php coding...)

Appreciate if anyone could assist...

What version of Zen Cart ? What patches have you applied?
What other addons are installed?
Did you have debug logging-to-file enabled when you encountered this? If so, please zip the logs and post a link where they can be reviewed.

My Zen Cart version is v1.3.7.1 [2007-07-13 23:30:27] (Fresh Installation)

Have not done any add on or apply any patches so far. Just install or I should say activated the original Paypal Express Checkout payment modules.

The attached is the log file containing the text file and the failure notice when return to my shopping cart.

Appreciate your assistance...

Try this:

edit /includes/modules/payment/paypalwpp.php
around line 519 you have:

     number_format($order_amount, 2),

change it to:

     number_format((isset($options['AMT']) ? $options['AMT'] : $order_amount), 2),

Then do another test transaction.


I'm stumped about why the order would calculate 0.04 for the details, but then send 0.01 as the final total.

Were you testing any coupons or gift certificates or group discounts in these tests?

around line 519 you have:

     number_format($order_amount, 2),

I noticed that there are couple of lines that contain number_format($order_amount, 2). Other lines include line 515, 579, 675,677,1674. Do I change all or just change the one in line 519 only?

Well, the default currency in my shopping cart has been set to MYR. It is converted to USD when the amount is parsed to paypal. Conversion rate: 0.278 . Would this cause the error?

Yes, I meant only the one line. Then retest.

Yes, that could cause it. What happens if you set the conversion rate to 1.0000 ?

Hi DrByte,

Thanks for your prompt response. Transaction successful.

Your first solution by changing just the line 519 works, but the charges that went through is USD0.04 as compared to if conversion were done on MYR0.04 = USD0.01 .

Although it has resolved and result in successful transaction, but another issue arise, i.e. instead of charging the client USD0.01, now the client is being charges USD0.04 . So is there anyway to resolve this new issue?

Can I have the following situation?
1. My shopping cart to allow the client to choose among 3 currencies, i.e. MYR (primary), SGD and USD for payment.
2. Check out using paypal. For SGD and USD, I believe Paypal has no problem as these two currencies are among those accepted. However for those that is not accepted, i.e. MYR, Paypal will default them to USD.
Can you assist in handling this situation?
