What's wrong with my code?

Hi!

Tried following along with the video, but can't seem to get the program to work. Can anyone help me?

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);

Thanks! R

It looks like you might have forgot the curly braces for your while statement.

Thanks for taking a look! I tried that, but still can't get it to work though!

My mistake, there is no need for curly braces with this while statement. The problem is your last line of code. You have an extra single quote in it.

It should be:

document.write('It took you ' + guessCount + '  tries to guess the number ' + randomNumber);
