The prompt dont print how many questions left...

I dont even see the first prompt saying how many questions left. if someone could point me in the right direction it would be appreciated.

var questions = 3;
var questionsLeft = '[' + questions +' questionsLeft]';
var adjective = prompt('Please type an adjective' + questionsLeft);
questions -= 1;
questionsLeft = '['+questions +'questionsLeft];
var verb = prompt('Please type a verb' + questionsLeft);
questions -= 1
var noun = prompt('Please type a noun' + questionsLeft);
questions -= 1 
alert('All done. Ready for the message?');
var sentence = "<h2>There once was a " + adjective;
sentence += ' programmer who wanted to use JavaScript to ' + verb;
sentence += ' the ' + noun + '.</h2>';
document.write(sentence);

Hey Ben,

You got a typo on Line 5 — you're missing a closing single-quote. Fix that and your code will run as you expect.

Unless you changed something else, it should run; that was the only thing that kept it from running in my console. The below code should run without error:

var questions = 3;
var questionsLeft = '[' + questions +' questionsLeft]';
var adjective = prompt('Please type an adjective' + questionsLeft);
questions -= 1;
questionsLeft = '['+questions +'questionsLeft]';
var verb = prompt('Please type a verb' + questionsLeft);
questions -= 1
var noun = prompt('Please type a noun' + questionsLeft);
questions -= 1 
alert('All done. Ready for the message?');
var sentence = "<h2>There once was a " + adjective;
sentence += ' programmer who wanted to use JavaScript to ' + verb;
sentence += ' the ' + noun + '.</h2>';
document.write(sentence);

I'm not sure what you mean, man; the questionsLeft is being decremented and displayed in the prompt view — is that not happening for you?

Here let's clean up your code a little bit so it reads better:

var remainingQuestions = 3; // Just a counter that we're going to subtract from...

var adjective = prompt("Please type an adjective. There are only " + remainingQuestions + " questions left!");
remainingQuestions -= 1; // Subtract 1 from that counter ...

var verb = prompt("Please type a verb. There are only " + remainingQuestions + " questions left!");
remainingQuestions -= 1; // Subtract 1 from that counter ...

var noun = prompt("Please type an noun. There are only " + remainingQuestions + " questions left!");
remainingQuestions -= 1; // Subtract 1 from that counter ...

// I use confirm() instead of alert() because it's options are "yes" and "no" — unlike alert's which is just a "cancel" button
// Really though, it doesn't matter. Your way works just as fine.
confirm("That's it, no more questions! Ready for this shit?");

document.write(
  "<h2>" +
  "There once was a " + adjective + 
  " programmer who wanted to use JavaScript to " + verb + 
  " the " + noun + "!" + 
  "</h2>"
);

Let me know if you have any questions.
