Program not compiling correctly
So i wrote this program and basically, I want it to add up the different devices purchased and list the amount of devices, total price(price of all the devices before tax),sales tax, and final price. Everything is working except the total price. For example if when prompted to select an item from the menu I press 10, which is the same is choosing nothing this works correctly. If prompted to select and item and I just choose one item it will calculate it and display it properly. However when i try to have the program calculate multiple purchases it only adds the last purchase thus giving me an inaccurate total price and sales tax, i'm not sure where i want.
Edit: Sorry I just figured out how to edit it properly.
