Cant figure out what I'm doing wrong withy method

it is saying I need to make sure I'm using the right decrement on barCount but I didn't use barCount I was using lapsDriven please help I'm lost.

GoKart.java 
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  private int lapsDriven;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }
  public void charge() {
    barCount = MAX_BARS;
  }

  public boolean isBatteryEmpty() {
    return barCount == 0;
  }

  public boolean isFullyCharged() {
    return MAX_BARS == barCount;
  }

  public void drive(int lapAmount) {
    lapAmount += lapsDriven;
    lapsDriven -= 1;
  }
}

In your drive method you need to decrement barCount using:

barCount -= lapAmount;
