This seems syntactically correct when compared with the video, but the program wont run, insight please?

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>'); }

This was hard to read - please try to format the code next time :)

You can do it like this

```javascript

<your code here>

```

Anyway - you're missing an end-parathesis in the if-statement which is inside your first if-else

This runs:

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) { //you were missing an ')' after '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>');
}

You're missing a curly brace right at the end. Also you are missinf an end bracket off of one of your if statements.

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>');
    }
  }
