No results display in preview?

I'm sure its something small, but nothing displays other than "let's Make Random Numbers" when I preview in workspaces. Even the JavaScript console is blank. I've done no editing to the index.html file.

var upper = 10000;
var randomNumber = getRandomNumber(upper);
var guess;
var attempts = 0;

function getRandomNumber( upper ) {
  return Math.floor( Math.random() * upper ) + 1;
}

while ( guess !== randomNumber ) {
  guess = randomNumber( upper );
  attempts += 1;
}
document.write("<p>The computer took " + attempts +  " to guess the number " + randomNumber ".</p>");

Not sure if this is it, but there's a missing + between randomNumber and closing p tag. Should be:

document.write("<p>The computer took " + attempts + " to guess the number " + randomNumber + ".</p>");

Change randomNumber to getRandomNumber, the function you created.

I believe he is not talking about the function. Looks like he just required the randomNumber function. If he called the getRandomNumber function, he would get a new value printed out.
