Solution doesn't work

JavaScript

In the JavaScript Data Structures curriculum, I am on the following lesson:

Basic Data Structures: Iterate Through the Keys of an Object with a for…in Statement

My solution matches the one in the guide, and yet it is not being accepted. The code is as follows:

function countOnline(usersObj) {
  // Only change code below this line
  let result = 0;
  for (let user in userObj) {
    if (userObj[user].online === true) {
      result++; 
    }
  }
  return result;
  // Only change code above this line
}

The output console displays the following:

// running tests
The function countOnline should return 1 when the object { Alan: { online: false }, Jeff: { online: true }, Sarah: { online: false } } is passed to it
The function countOnline should return 2 when the object { Alan: { online: true }, Jeff: { online: false }, Sarah: { online: true } } is passed to it
The function countOnline should return 0 when the object { Alan: { online: false }, Jeff: { online: false }, Sarah: { online: false } } is passed to it
// tests completed

Does anyone know what the problem is? Thank you in advance.

Your function argument is named usersObj and you’re iterating over userObj in your for...in loop.
