I'm using LabView and I need help with the program, am I supposed to use nested case structures and for loops?

Edit: The program I'm using is LabView.

You are responsible for setting up a pay station at a movie theater. You sell the following items according to the following prices Small Medium Large Pizza Plain Vegetarian Pepperoni 10 12 13.2 14.4 8.8 9.6 12 Ice Cream Cone Shake Sundae 3.2 4 4.8 4 5 6 4.8 6 7.2 Snack Candy Bar Soda Popcorn 0.8 1.6 2.4 1.2 2.4 3.6 2 A customer can order as many items as they want and you need to calculate a total price. You will have 3 inputs an item: (Pizza, Ice Cream.), variety: (Plain, Vegetarian..., and size: (Small, Medium...). The user will have a combo box to select these different options. Then add up each items cost and display the total. If the user selects something that is not possible like Pizza, Cone add 0 to the total (You can do this using the default option). Also make a note in the wrong items array as to which items were wrong so the cashier can fix them (make sure the first item is 1 and not 0). So if the oth element in the array is wrong then the wrong item list should have 1 as its first value. You are responsible for setting up a pay station at a movie theater.
