I am having some trouble with my code. For this code, I am letting the user choose everything from the menu and let them pick what they want to do. Add, subtract, multiply, divide....One of the option is #6, where the user has the choice to be able to change the numbers again. Unfortunately, I am having trouble with that option to work.
