Any idea why code won't execute?

For the "Do While Loops" Javascript tutorial I have an exact mirror of the code the instructor has in the video, but when I save and preview my code nothing happens!

In the Javascript console, I am seeing an "Uncaught Syntax Error: Unexpected token =" for Line 14. Please see my code below:

var randomNumber = getRandomNumber(10);
var guess;
var guessCount = 0;
var correctGuess = false;

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

do {
  guess = prompt('I am thinking of a number between 1 and 10. What is it?');
  guessCount +=1;
  if (parseInt(guess) ==== randomNumber) {
    correctGuess = true;
  }
} while ( ! correctGuess )
  document.write('<h1>You guessed the number!</h1>');
document.write('It took you ' + guessCount + ' tries to guess the number ' + randomNumber);

Any feedback would be much appreciated. Thanks! BTW, I am using Chrome as my browser. Also tried Safari, but still running into the same problem.

You have 4 equal signs in a row in your if statement on line 14. Change it to 3 equal signs.

if (parseInt(guess) === randomNumber) {
    correctGuess = true;
  }

(Facepalm) I completely missed that, lol. Thanks for pointing that out.

However, I did remove one of the equal signs and am still running into the same problem:

var randomNumber = getRandomNumber(10);
var guess;
var guessCount = 0;
var correctGuess = false;

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

do {
  guess = prompt('I am thinking of a number between 1 and 10. What is it?');
  guessCount +=1;
  if (parseInt(guess) === randomNumber) {
    correctGuess = true;
  }
} while ( ! correctGuess )
  document.write('<h1>You guessed the number!</h1>');
document.write('It took you ' + guessCount + ' tries to guess the number ' + randomNumber);

I'm confused when you say you're "running into the same problem." You should at least be getting a different error message.

Nope. It's crazy, I know. When I try to preview the code the page is still blank, and in the Javascript console it still says "Uncaught Syntax Error: Unexpected token =". Also still showing script.js:14

Oddly, when I look at line 14 in the console, it's not highlighting anything out of the ordinary (like it did when I had the 4 equal signs).
