Many articles here deal with the the annoying fact, that you had to "extra" press the "update" button in your shopping-cart to update the number of products ordered. In response to this and to make my and your customers shopping easier, I have contributed this tiny, but I find extremly important module. Here you have a drop down button to change the number of products ordered. And the number is changed instantaniously for your billing. So it cannot happen any more, that a customer forgets to press the "update" button and gets the wrong number of articles. The number displayed in the drop down button can be changed in the your admin. ENJOY!!
