Get the customer to Checkout after Adding to Cart

Hi,

The fefault in my OpenCart store is:
Customer Adds to Cart --> A small notification appears at the head of the page --> Customer stays in the same page.

I want the customer who just added a product to his shopping cart to be directed to Checkout page (http://noajewelry.com/index.php?route=checkout/checkout)
or to his Shopping cart (http://noajewelry.com/index.php?route=checkout/cart)....


thanks,
Amrami
