I am making an invoice for a company i work for and ive made it so far so
that you select from a drop box the type of product and it requeries another
drop box to show the different products and once you select one it displays
the price in a list box. i want to have a sub total, tax, and total
automatically tallied and to do that i have to add the values from list boxes
on the page, i have ten made because the invoice allows up to ten products to
be sold at a time. so how do i add the list box values (there is only one
item in each of the list boxes: its price).
