You didn't make a private int named lapsDriven, at the top under your private int barCount, you need to make a new private int. You also have your drive method commented out. Your method is a boolean and should be void because it returns nothing, you tried to create a new private int named lapsDriven inside of your method which you cannot do, it needs to be at the top. It should look like: public void drive() { lapsDriven++; } and you should have the private int lapsDriven where your other variables are.
