Add to cart button sends to checkout

I am developing a website here - jeyjoo.it/it/shop/ with latest Hika shop non commercial version and Joomla 3.1.5
Every time I click add to cart, the user is sent to the shopping cart. I would the user to carry on shopping.

I read a few forums saying to that there is an option in the admin panel under /COmponents/Hika shop/checkout , but I dont seem to have that option.

Any ideas,
Thanks

Hi,
If you don't want your customers to be automatically redirected to the checkout, you'll have to set the "After a product is added to the cart" option to Always stay on the same page or Stay and display a popup notice through "Hikashop->System->Configuration->Main"

Thanks - I had missed this
