My program won't run when I preview it, I can't find what's causing the problem, please assist?

My syntax looks the same, I can't find the source of the problem, but when I preview it it doesn't run.

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>');
}

Assuming you intended to have nested if/else if statements. the only problem I see is that you are missing a closing parenthesis on line 8. View below

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

I hope this helps.

One way to find what the problem is, is to use console.log. I would add console.logs in your conditional statements and and see which ones are firing and which ones are not, that way you can see where the issue is.
