Show inc Tax price at Checkout

Hi Nicolas

I would like to know how to make the inc Tax price show on the checkout, instead of the ex tax price please.

All the links to the supposed answer, end up on a BRAVO page.

The inc Tax shows correctly in the Shopping Cart module, it's only when you click "Proceed to Checkout" that the ex-tax price then shows up with the corresponding Taxes added on another line. I'd like to keep the Tax line, but show the Full Price including tax ...

Shipping price is all correct.

EDIT: i found this post:

For that, you can add the line
$this->params->set('price_with_tax',1);
after the first <?php tag of the file "step" of the view "checkout" that you can edit via the menu Display->Views

and I added it here:
<div id="hikashop_checkout_page" class="hikashop_checkout_page">
<?php
$this->params->set('price_with_tax',1);
if(hikashop_level(1)){.........

then cleared cache, but it still shows ex tax price??
