Why won't this work?

Why is no prompt box showing up? Here is the 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); i (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>'); }

Hey Samuel!

It looks like your logic is actually correct so brownie points to you for that! The issue seems to be Syntax related. There were some syntax issues that needed to be corrected. For ex: on your two else if clauses, your guess and guessLess parameters were not actually within the parseInt function. they should look like: parseInt(guess). You were super close!

Here is a copy that works:

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>');
}

Feel free to compare mine with yours and look closely to see the differences. Let me know if this helps or if you have questions! :)

Sorry, I'm not sure why the syntax highlighting of my code seems weird. Not sure what is causing that. :/ hopefully you can still read it.
