My code won't work when I preview in Chrome browser, but it will when I cut and paste it into console...

Hello! I'm a JavaScript newbie so really could use some help. Lately when I try running my code that I'm working on from workspaces the only thing that shows up is the Title from the HTML but the code doesn't actually appear to run. Here is what I'm trying to run right now...

function randomNumber(upper) {
  return Math.floor( Math.random() * upper ) + 1;
}
var counter = 0;
while (counter < 100) {    //this code states that as long as the count variable is less than 10 to keep running the loop
  var randNum = randomNumber(6);
  document.write(randNum + ' ');
  counter += 1;        //this code states to add 1 after each loop
}

HOWEVER; when I open up the console and cut and paste the code in there it will show the random numbers I asked for but not the HTML Heading.

Can someone please tell me what I'm doing wrong? Thanks!

I was testing your code and it runs fine. Just revised it for my own testing:

function randomNumber(upper) {
    return Math.floor(Math.random() * upper) + 1;
}
var counter = 0;
while (counter < 10) {
    document.write(randomNumber(6) + ' ');
    counter ++;
}

Have you included the js file in your html file? Or have you included it correctly?

<script src="myscripts.js"></script>

Change myscript.js to your js file name. Make sure you get the name right and its in the same folder.

Did you include the .js file within the html file. You should be able to see something like this in the html index file.

<script type="text/javascript" src="YOUR JS file"></script>

Thank you for your replies! Simple mistake, I was using a workspace from a different video so the js file did not link correctly. Thanks for your help! :D
