[Done v1.3.9h] SGS-002301 Linkpoint error in 1.3.9g

Dr Byte - There are many prior threads about this, but I don't know if this is exactly the same because no coupons or GV's are being used. It's the dreaded SGS-002301 response code.

Response Code:  SGS-002301: Charge total must be the sum of subtotal, tax,
value added tax, and shipping.

=================================

Sending to Gateway: 
result = LIVE
oid = 29388-0tuOd5
subtotal = 7.28
shipping = 2.07
tax = 0.64
chargetotal = 9.98

As you can see from above, if you add all the values, it equals $9.99 instead of $9.98. No coupons are being used. Any ideas?

Just to add, the chargetotal is off by one penny when you add up the values. I do see the following code in the API around Line 434, but I don't want to touch anything or else more stuff will break!

 // resubmit without subtotals if subtotal error occurs
    if ($result["r_approved"] != "APPROVED" && !($result["r_approved"] == "SUBMITTED" && $result["r_message"] == 'APPROVED')) {
      if (in_array(substr($result['r_error'],0,10), array('SGS-002301', 'SGS-010503'))) {
        foreach(array('items', 'subtotal', 'tax', 'shipping') as $i) {
          if (isset($myorder[$i])) unset($myorder[$i]);
        }
        $myorder["oid"] .= '-b';
        [b]$myorder["chargetotal"] = ($myorder["chargetotal"] - 0.01);[/b]
        $result = $this->_sendRequest($myorder);
        if (!is_array($result)) {
          $messageStack->add_session('checkout_payment', MODULE_PAYMENT_LINKPOINT_API_TEXT_FAILURE_MESSAGE, 'error');
          zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL', true, false));
        }
      }
    }

I didn't know if adding a THIRD block option would work. For example, if the above code fails, do again but ADD one penny or something. I guess I would need to see if more failures occur due to it being off by a penny or not.

In the meantime, any idea or tweak to allow something like the above transaction to process?

That section of code is not relevant to the logs you posted. It is not the cause of your problem. Thus a "THIRD block" would be pointless.

Do you have any other ideas, Dr Byte? Or is there any other thing I can send to help troubleshoot why it would be off by one penny? Right now, my LinkPoint module is set debug mode: Failure Alerts Only.

It's just weird because other orders place fine into the system, but since the upgrade, we're seeing quite a few of these SGS-002301 errors all of the sudden.

Upgrade from which version?

To investigate further, I'll need to know exactly how to recreate this exact transaction scenario from a fresh clean uncustomized install. ie: currency used, tax rates, shipping rates, product price, etc.

Here's what the latest customer did to reproduce.

Add the following two items to the shopping cart:

• http://www.mjmmagic.com/store/bending-fractured-metal-fork-p-4873.html
• http://www.mjmmagic.com/store/snake-mustard-jar-p-4872.html

Make sure you're registered with a California address so tax will be applied. When you get to the checkout area, it should list the following:

subtotal = 7.70
shipping = 2.92
tax = 0.67

That adds up to $11.29, but the linkpoint module is processing $11.30, thus giving the error.

I'm trying to reconstruct it.
Is that an 8.7% tax on products only, with no tax on shipping?

It's a 8.75% tax on California purchases. I imagine it's rounding that amount up (due to the .75 percentage) and making it a 8.8%? I think the common denominator is that all these examples I see are all from people getting charged Sales Tax. However, it's not ALL orders with sales tax. We have many California purchases which go through just fine....but when we have an error described in this thread, they are always orders with California tax being calculated.

I can't seem to repeat the problem. Maybe it's because I'm using slightly newer code.

Try this updated module to replace your current v1.3.9g version of the file:
