The problem is that all of your code is in person.js. You seem to be adding Teacher() inside of person.js. You should be adding that code in teacher.js. There are two tabs and the challenge starts on person.js. Just click the other tab then alter the Teacher() constructor function. You're function is correct, you just have it in the wrong file.
