Tell us what’s happening:
Describe your issue in detail here.
Is this coding challenge broken? I was having a hard time, so I tried the solution available from freeCodeCamp and it still returned with failed tests. But if I changed the data in the object key values the data the tests were testing for would be correct.
Your code so far

const users = {
  Alan: {
    online: false
  },
  Jeff: {
    online: true
  },
  Sarah: {
    online: false
  }
}

function countOnline(allUsers) {
  // Only change code below this line
let count = 0;
for (let prop in users) {
 if (users[prop].online === true) {
   count++;   
 }
  // Only change code above this line
}
return count;
}
console.log(countOnline(users));

It looks like you copied the answer incorrectly. I wouldn’t do that. (Copy the answer at all, let alone incorrectly)

Your function needs to totally ignore the global variable.

I try not to until I’m at a total loss. Thanks for the help!

It can get frustrating for sure. Luckily, those of us on the forum have made thousands of mistakes, so we can usually spot what the mistake is pretty quickly.
