Javascript basics, what is my mistake?

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>');
}

Hi Liam,

You are missing a "}" in your last else if statement. Here is the fixed code:

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;
    }
}

Hope that helps.
