Identical code, different results?

As far as I can tell, I've reproduced Andrew's code exactly, but when I click on the HTML/CSS button upon previewing the page, the number doesn't change from 1.

The dice.js file:

var dice = {
  sides: 6,
  roll: function() {
    var randomNumber = Math.floor(Math.random() * this.sides) + 1;
    return randomNumber;
  }
}

And the ui.js file:

function printNumber(number) {
  var placeholder = document.getElementById("placeholder");
  placeholder.innerHTML = number;
}

var button = document.getElementById("button");

button.onclick = function() {
  var result = dice.roll();
  printNumber(result);
};

A fresh pair of eyes to look here and tell me what I'm doing wrong would be great! I'd like the output of my code to mimic how the number changes at the end of the video.

Have you saved your progress and tried relaunching it? The behavior that only display 1 is coming from default workstation setup for the project. Your code works as expected there should be no place in your code that will always generate 1.

I tried myself and then I tried it using your code and both produce same result.

If problem keeps happening upload your workstation environment.

I had tried that before but I just relaunched the Workspace and it finally works as it should!

Thanks for your help. :)

This was a little buggy for me too. But did end up working.
