Choice 2 in menu is the main question: If the first number is not in the roster, the user is prompted for another jersey number but when that one is also not in the roster, the code fails and there is an error message. How do I fix this code so that no matter how many numbers it prompts for that will keep asking until they are in the dictionary?
