I have a jQuery Function that loops, dynamically, depending on how many items are in a shopping cart. For example, if there is one item, there is one jQuery function. If there are two items, there are two jQuery functions, etc... Each function creates a specific var called PRICE. So, if I have three items in the cart the jQuery function loops three times and I have thee price vars. price_1, price_2, price_3, etc. When the function is done looping I would like to add all three vars to get a total. I have no idea where to start.
