Display Quantity 0 in product listing

-- url of the page with the problem --http://harp1009.staging-cloud.netregistry.net/index.php/store/category/14-rental-harps
-- HikaShop version -- :2.2.0

In product listing I would like to display "on hire' when I set the quantity of the product to 0.
I am not displaying price. This was done by editing the CSS
I guess the text ' on hire' is done with a language overwrite - but how do I get the ) quantity to show in the listing?

Cheers,

Thomas

Hi,

You'll probably be able to do it by editing your translation file through "Hikashop->System->Configuration->Language->'Your language file'" and changing this line : By :
