I'm pretty sure I did this correctly. It's not letting me pass. This question space needs more characters also!

this is the code i entered. i also researched online, and i don't see the problem:

function Teacher(firstName, lastName){ Person.call(this, firstName, lastName); }

person.js 
function Person(firstName, lastName) {
  this.firstName = firstName;
  this.lastName = lastName;
}

Person.prototype.fullName = function() {
 return this.firstName + " " + this.lastName; 
};

function Teacher(firstName, lastName){
  Person.call(this, firstName, lastName);
}
teacher.js 
function Teacher(firstName, lastName, roomNumber) {
  this.firstName = firstName;
  this.lastName = lastName;
  this.room = roomNumber;
}

It looks like you were working in the wrong file (tab).

Task 1 tells you to make changes to the Teacher constructor function, and that function is located in teacher.js. But it looks like you added new code to person.js.

Hint: everything you add or change for this challenge will go in teacher.js.
