Display price on product page

-- HikaShop version -- : 2.2.0
-- Joomla version -- : 2.5.14
-- PHP version -- : 5.3

I have created a product, in the product parameters "display price = off". In the product listing there is no price shown, so that's okay. On the product page, however, the price is still there. If I change the price to 0, it shows "free" on the product page.

How can I make the price not to display on the product page ? € 0 is no option, because I also have free products. It's about products that don't have price (yet).

Kind regards,

You say

in the product parameters "display price = off"

but I don't know of such option for each product.
Could you do a screenshot of that page ?
As far as I know there is no option to say that you don't want to display the price for some products besides setting no price and changing the "free" word to something else via a translation override.
You would have to enter a specific price and then edit the file "listing_price" of the view "product" via Display>Views to remove the price display if the price is that specific price:
<?php if($this->row->prices[0]->price_value==11.11) return; ?>
