title: How to get and set price from arraylist?
body: <p>I am trying to get and set the price from my order form to the order summary.  Will you take a look at my code and see what I am doing wrong? </p>
  
  <p>My assignment requires me to use an arrayList and a JOptionPane to list out the orders and totals.</p>
