This script allows you to offer a running total using checkboxes/product not a quantity, only the checked products are added to the total and sent to the cart.

In the script, if the total products is for example 10, then increase the line for:
(i=1; i<10; i++) {
to 11
(i=1; i<11; i++) {
always increase the number by one to the total number of your products.
