cant find the error in my code

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>');
}

On the second line, at the end of the randomNumber, you had an out of place parenthesis. Took that out and it seems to work fine 

var correctGuess = false; 
var randomNumber = Math.floor(Math.random() * 6 ) + 1;//you had a ) here 
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>'); }
