Help trying to insert JScrollPane into code

Question

Yes! It is me again on the same program. I have the program working with a few peoples help on this board. But, I want to make the display look better. So, I thought I would use the JScrollPane component. But, I'm getting a cannot resolve symbol error on the following statement.
f.setContentPane(scrollPane);
The code is below. Any help in getting the JScrollPane to work would be very appreciated.
Code:
