title: If/Else calculations through JOptionPane
body: <p>I am trying to calculate this if/else statement through the JOption Message window. Prompt 1 is fine and returns the name, but I am not getting any calculations through prompt 2. I'm guessing I need to do something with my double number1, but I'm not exactly sure.</p>
  
  <p>Thanks in advance!</p>
