What is wrong with this snippet?
var questionCount = 3;
var questionsLeft = '[' + questionCount + ' questions left]';
var adjective = prompt('Please type an adjective ' + questionsLeft);
questionCount -= 1;
var verb = prompt('Please type a verb ' + questionsLeft);
questionCount -= 1;
var noun = prompt('Please type a noun ' + questionsLeft);
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);
MOD: Edited question to format the code.

231,271 PointsIt's a bit hard to read without formatting (there's a video on code formatting), but I can see that "questionsLeft" is not being updated between questions, so each prompt will say "[3 questions left]".
A quick fix would be to reset it each time "questionCount" is changed:
questionCount -= 1;
questionsLeft = "[" + questionCount + " questions left]";

I believe the key issue here was your train of thought when using the variable 'questionsLeft'. You cannot iterate a string and that is what 'questionsLeft' is--a string. You can iterate a number ! If you want clarification go ahead and reply and hopefully I'll get a notification.
Cheers !
var questionCount = 3;
var questionsLeft = '[' + questionCount + ' questions left]';
var adjective = prompt('Please type an adjective ' + questionsLeft); // use questionCount instead and add + 'questions left'
questionCount -= 1;
var verb = prompt('Please type a verb ' + questionsLeft); // questionCount and add + 'questions left'
questionCount -= 1;
var noun = prompt('Please type a noun ' + questionsLeft); // questionCount and add + 'questions left'
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);
The code after fixed (multiple solutions): My solution was that I made questionsLeft a string and added questionCount. One thing I didn't do was keep the brackets []. You could add those in.
var questionCount = 3;
var questionsLeft = ' questions left';
var adjective = prompt('Please type an adjective ' + questionCount + questionsLeft);
questionCount -= 1;
var verb = prompt('Please type a verb ' + questionCount + questionsLeft);
questionCount -= 1;
var noun = prompt('Please type a noun ' + questionCount + questionsLeft);
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);
