LinkPoint Error - Total Not Matching

[itwebsolution]

There has been an error processing your credit card, please try again : CC-4019: Total charge amount did not match sum of the subtotal, shipping, tax and vattax amounts. 

 

This error is occuring on selected products. I have updated with the latest version of the LinkPoint contribution and set the sub-total to come after any discounts. The error occurs regardless if a user is using a discount voucher or not. How do I verify that the Order Total calculations are not being rounded incorrectly?

try this (taken from LinkpointMS1 V1.5 contribution--which isn't available anymore in contribution listing... don't know why):

Simple really, just had to figure out the "PHP" way to do it. Just a couple of edits so I won't include full files.

 

In /catalog/includes/modules/ot_coupon.php:

 

Find lines:

 

if ($od_amount > 0) {

      $order->info['total'] = $order->info['total'] - $od_amount;

 

Add this line right after:

      $_SESSION['od_amount'] = $od_amount;

 

In /catalog/includes/modules/ot_subtotal.php:

 

Find lines:

 

      function process() {
     global $order, $currencies;

 

Add right after:

 

      $od_amount = $_SESSION['od_amount'];
     $subtotal = $order->info['subtotal'] - $od_amount;
     $order->info['subtotal'] = $order->info['subtotal'] - $od_amount;

 

Then, make sure the sort order of the payment lines (via OSCommerce admin

site) puts discount before subtotal.

 

Essentially, I just used the global PHP session to make the discount amount available in the standard subtotal routine. There may be more correct ways to do it but it works.
