What's wrong with my code?

Hi!

Tried following along with the video, but can't seem to get my code to work for some reason. Can anyone tell me if i've made an error in my code? I used the developer tool in Chrome, and it's showing that there's a syntax error on line 20. It's just a closing curly bracket, so not sure what is wrong with this...

Here's my code below.

var correctGuess = false; var randomNumber = Math.floor(Math.random() * 6 ) + 1; var guess = prompt('I am thinking of a number between 1 and 6. What is it?'); if (parseInt(guess) === randomNumber ) { correctGuess = true; } else if (parseInt(guess) < randomNumber) { var guessMore = prompt('Try again. The number I am thinking of is more than ' + guess); if (parseInt(guessMore) === randomNumber) { correctGuess === true; } } else if (parseInt(guess) > randomNumber) { var guessLess = prompt('Try again. The number I am thinking of is less than ' + guess); if (parseInt(guessLess) === randomNumber){ correctGuess = true; } if ( correctGuess ) { document.write('<p>You guessed the number!</p>'); } else { document.write('<p>Sorry. The number was ' + randomNumber + '.</p>'); }

Thanks for your help! R

Hi Rahim,

Looks good to me, though I noticed in your code above, you are missing the final curly bracket. This code works fine in Chrome:

var correctGuess = false;
var randomNumber = Math.floor(Math.random() * 6 ) + 1;
var guess = prompt('I am thinking of a number between 1 and 6. What is it?');
if (parseInt(guess) === randomNumber ) {
    correctGuess = true;
} else if (parseInt(guess) < randomNumber) {
    var guessMore = prompt('Try again. The number I am thinking of is more than ' + guess);
    if (parseInt(guessMore) === randomNumber) {
        correctGuess === true;
    }
} else if (parseInt(guess) > randomNumber) {
    var guessLess = prompt('Try again. The number I am thinking of is less than ' + guess);
    if (parseInt(guessLess) === randomNumber){
        correctGuess = true;
    }
    if ( correctGuess ) {
        document.write('You guessed the number!');
    } else {
        document.write('Sorry. The number was ' + randomNumber + '.');
    }
}
