Hi Andrea,

While we are trying to get the string out of myString, we would try to use the key instead of the value to fetch it. 

const myString = {
    string: "Programming with Treehouse is fun!",
    countWords: function(){
        const wordArray = this.string.split(' ');
        return wordArray.length;
    }
}

myString.characters = myString.string.length;
var numWords = myString.countWords();

Hope that helps!
