Hide Price in the Product Page

How do I hide price. I left the price BLANK. Now it is showing "FREE" I have configure it now to displace prices. That did not work.

Attached jpeg files.

I tried this as suggest on the forum. So I add this to the Hikashop front end CSS. It did not work

.hikashop_product_page span.hikashop_product_price_full{
display: none;

I am using Joolma 3.x with the latest hikashop 2.11

You need to use a translation override to change the Free text into something else:
