Typo.

- output.inerHTML = message;
+ output.innerHTML = message;

Hello :)

You've made a spelling mistake in this bit of code:

function print(message) {
  let output = document.getElementById(`output`);
  output.inerHTML = message;
}

To be precised - it should be "innerHTML", not "inerHTML".

I hope it helps!

Thank you so much, wonderful people!

No problem.

FYI — I debugged by pasting your code right into Chrome's Dev Tools console. It came back with this error which was easy to pinpoint the mistake:

VM4561:37 Uncaught TypeError: Cannot set property 'inerHTML' of null
    at print (<anonymous>:37:19)
    at <anonymous>:54:1
