OT coupon code tax error of excluded products

[Calljj]

in the includes/modules/order_total/ot_coupon.php the tax amount of an excluded product is removed twice from the total price resulting in unexpected amount showing as part of the order total.


approx line 620 gives:

        if ($this->include_tax == 'true') {
         $orderTotal -= $productsTaxAmount;
        }
        if (DISPLAY_PRICE_WITH_TAX == 'true')
        {
          $orderTotal -= $productsTaxAmount;
        }

resolution appears to be chnging if to include 'or' or simply removing second 'if' statement

Yes an "or" probably makes sense.

If anyone would like to build a PR, that would be great.
