Issues with my do while. And trouble with adding my stored array info.

scuba steve (5)
I am having trouble with getting my do while loop to function correctly and I can't figure out how to get a totals for my sales price, sales tax and cash price from my Price_data array in my totals array in separate columns. I have a function set up on getting my totals for each one but i can't think of a way to get each one from the data array and add them together into my totals array. If anyone can please give me any tips on how to get them to work correctly I would greatly appreciate it. I've been trying for a while now and I just can't find a way to get my total function to work.
