title: Asks for input but doesn't acknowledge
body: <p><strong>When you Run the program and  select something it sometimes doesn't acknowledge the input. Sorry if there is a obvious mistake. I am still quite new at this. Thanks for all the help in advance.</strong>
  This is not a major problem but it is for a school thing so preferably I would like to fix it.</p>
