Paypal Express Checkout error when using Coupons

[Mole_LR]

Hi!

Joomla 2.5.20.
VM 2.6.0a (also for 2.6.0 the same, therefore updated, hoping that it will work, but - not ;-()!

Set Paypal plugin for Express Checkout! All works fine - in cart pressing appropriate button, it redirects to the Paypal! BUT, when I create Coupon (no meatter - permanent or gift, the same problem) and use it in Cart, after applying it, Paypal Express Checkout does not work - it returns error: "An error occurred. The payment has not validated. Please choose another payment"

Debuggin returns error in Total number:

"10428: Handling total is invalid."


"PayPal response::

Why - I do not know...

Tested with 2 different environment, 2nd one - fresh Joomla and VM install, nothing else!

Quite important thing for me... I think - it's bug, because - why normally it works, but just using Coupon - it does not work?

Thank You!

P.S. With discounts all works fine...

Hi Mole_LR

Did you manage to find a solution? It happens to me too. I talked to paypal support and they detected the problem. It is caused by the variables that the cart uses when checking out. One of them, PAYMENTREQUEST_0_HANDLINGAMT, is negative so it should not be used, instead, they suggested a different variable that should be use which allows negative numbers, however, I have to clue on how to fix it either.

Pretty sure Alatak ( she does the plugins) knows about it and will action

[Bichito82]

She does know I believe, and said would try it out. We are all expecting a fix, I am sure that it is easy to accomplished for someone with knowledge. Lets keep our fingers crossed

Hello
Yes there was another post about . I am going to check it. Thanks

[alatak]

Hello

Why in your case you have this

One of them, PAYMENTREQUEST_0_HANDLINGAMT, is negative so it should not be used,

Can you try the version attached. Replace the paypal folder in plugins/vmpayment
Thank you.

Hi, i have the same problem, but the paypal.zip didnt solved my problem, any ideas?

VirtueMart 3.0.12

Joomla! 3.4.8

I am encountering exactly the same problem when trying to apply a 10% coupon using PayPal Express Checkout. The VM calculates the discount correctly but, when the payment is sent to PayPal it returns error: "An error occurred. The payment has not validated. Please choose another payment"

The error log is:

2016-02-13 15:17:22 ERROR vmError: 10413: The totals of the cart item amounts do not match order amounts.<br />
2016-02-13 15:17:22 ERROR plgVmConfirmedOrder, response:: Array

    [payer_id] => TXJDBGQ6Nxxxx
    [first_name] => WENDY
    [last_name] => xxxxxxx
    [payer_email] => xxxxxx@gmail.com
)

(I have added xxxx to protect any possible confidential information)

I would be interested to know if the zip file shown as a fix would work on this latest version of VM. I would prefer not to overwrite a newer version with files designated for an earlier version in case I cause any further disruption.

If anyone has managed to come up with a newer fix I would welcome any response.

Incidentally, it works fine if a coupon code is not used, and I have also tried using one page checkout as well as disabling OPC but with no luck.

Rgds, Mark

Further to my last, and perhaps to simplify the problem:

I have a product priced at £6.25.

The coupon 10% gives VM checkout page a value of £0.63 (it has rounded up - although I have not checked the box in CONFIG>PRICING>ROUND ONLY DISPLAY

The total showing in the cart is thus £5.63.

When I am directed to PayPal, the amount is £5.62 !!

Who has stolen my penny?
