I have a dropdown list of bank account numbers, each number has an available balance. what I want to do is when I pick a number from the list it shows an output box saying "Available balance is x". my only concern for now is the front end so I just want to print a random number each time.

I tried using outputbox in JSF but the problem is the box is always there, I just want it if I picked a number.
