VAT TAX in product in discount

[marvays]

I have problem.
in invoice email and order page i have VAT.

If i have discount product i see this:
SKU | Product name | Price without VAT before discount | Qty | VAT after discount * Qty | Discount | Total price

this setup is bad for me. If i reed from left, i see "product name, with price, how much i add to cart, how much is TAX after discounted product, how much have discount and total price for this line.

I need change TAX "after" discount to "before" . . . . now i can see price + tax - discout = total.

In <td > i see:

Code Select Expand

<?php echo "<span  class='priceColor2'>".$this->currency->priceDisplay($item->product_tax ,$this->user_currency_id, $qtt)."</span>" ?>
how i can change it for me?

thx

Maybe you just need to change your discount rule to before tax?
