There is another bug on my page, which Tracy found, and I would need to find a way to prevent. User may click on Add to Cart button, then immediatelly click on Select All. The checkbox become selected, but the resulting page displays a message, User doesn't select anything. E.g., I have to find a way to process my form immediatelly after the Add to Cart button is clicked, therefore user (even the quickie) would not be able to click on Select in between...
