Hi there,

You want to change the code in applyDiscountCode to set this.discountCode to the returned value sent back from normalizeDiscountCode.

At the moment, you have this code:

  public void applyDiscountCode(String discountCode) {
    this.discountCode = discountCode;
  }

To the right of the equals, call normalizeDiscountCode and pass in discountCode as the parameter.

Then, in normalizeDiscountCode make it return a String as well as receive a String in the method skeleton. Inside the method, return the String it receives as you call toUpperCase() on it; use dot notation.

I hope that helps.

Steve.
