I've been experimenting with both Shop Made Simple and Cart Made Simple.
At this point I'm able to put some products inside what appears to be my Cart.
However when I view my Cart, the only thing I can do is remove products from it or change the number (if that works as I've read in some other posts).
What I'm not able to achieve (yet) is how to "submit" the cart-contents towards processing the order.

I guess I must have overlooked something but I cannot figure out where I went wrong

There are so many trees blurring my view that I cannot see the forest anymore

Thanks for any hints.
