Error making Bookmarklet

1

I have made a code that works perfectly


var lowerLimit = 1;
var upperLimit = prompt("Guess a number 1 to...");
var tries = 1;
var answer = Math.floor(Math.random() * (upperLimit - lowerLimit + 1)) + lowerLimit;
var guess = '';
while (tries > 0) {
    
guess = prompt('Try #' + tries + '\nGuess a number between ' + lowerLimit + ' and ' + upperLimit + ':'
, guess);
			
    if (guess == null) {
			alert('Bye! The answer was ' + answer);
        break;
    }
    if (guess == NaN) {
        alert('Bye! The answer was ' + answer);
        break;
    }
    else if (isFinite(guess) && guess != '') {
        guess = +guess;
        if (guess < lowerLimit) {
            alert('Your guess should be no less than ' + lowerLimit + '.');
        }
        else if (guess > upperLimit) {
            alert('Your guess should be no greater than ' + upperLimit + '.');
        }
        else if (guess > answer) {
            alert('Your guess is too high.');
        }
        else if (guess < answer) {
            alert('Your guess is too low');
        }
        else {
            var listTries = tries + 1
				alert('Great job, you got ' + answer + ' in ' + listTries + ' tries!');
            break;
        }
    }
    else {
        alert('Bye! \nThe answer was ' + answer);
			break;
    }
    
    tries = tries + 1;
}

It works, but not as a Bookmarklet. I made itHERE
by pasting the code in top the input. Please help!!!

You have to drag the bookmarklet link (Bookmaklet: bookmarklet < this is the link) to the bookmarks (for example to the bookmarks bar), or you have to copy the output (the code is wrapped inside a function) and create the bookmark manually using the output for the URL (this may or may not work).

Your code works for me as a bookmarklet when I drag it to the bookmarks bar.
