make sure that you actually call the funciton with questions in your solution box.

Ex; function x( array){....};
x(questions);

i had a similar problem and after i put that after my function in the solution box it worked

Sorry for the later reply. JosephBNolan it's usersAnswer not userAnswer.

Here's why I think you got it wrong

1. your parameter in the function is arr
2. the array in question is called questions

I don't believe the code kata inputs the questions array into any function.
