I've been working on a Magento website: satcogrowlight.com
I am very new to working with Magento in the back end.
My problem is that once I've added an item to my cart, I cannot change the quantity in the cart. I enter in the new quantity, click "Update Shopping Cart", the page refreshes, and everything remains the same.
I have no idea where to start troubleshooting. I haven't made any changes to the code, as far as I remember.

you have to include the form key,in cart.phtml.
