Number of questions not subtracting

The code below runs, but the number of questions after each prompt never goes down, i.e. it always reads "[3 questions left]". I thought I was identical to the example in the video, but would appreciate a set of fresh eyes. Thanks!

Code: 

var questions = 3; 
var questionsLeft = ' [' + questions + ' questions left]';
var adjective = prompt('Please type an adjective' + questionsLeft);
questions -= 1;
questionsleft= ' [' + questions + ' questions left]';
var verb = prompt('Please type a verb' + questionsLeft);
questions -= 1; 
questionsleft= ' [' + questions + ' questions left]';
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);

Hi Stephan,

It seems that you had a couple of typos in your code. Some of your "questionsLeft" variables didn't match up. I have modified your code for you below.

var questions = 3; 
var questionsLeft = ' [' + questions + ' questions left]'; 

var adjective = prompt('Please type an adjective' + questionsLeft); 
questions -= 1; 
questionsLeft = ' [' + questions + ' questions left]'; 
var verb = prompt('Please type a verb' + questionsLeft); 
questions -= 1; 
questionsLeft= ' [' + questions + ' questions left]'; 
var noun = prompt('Please type a noun' + questionsLeft); 

alert('All done. Ready for the message?'); 
var sentence = "There once was a " + adjective; sentence += ' programmer who wanted to use JavaScript to ' + verb; sentence += ' the ' + noun + '.'; 
document.write(sentence);

Hope this solves your issue!

Each time your prompt references the variable questionsLeft which remains the same throughout the program. It should reference questions as that is the one you are subtracting throughout.

Check for typos.

For example: These are two different variables only because of one Capital or Lowercase letter.

var myVariable = 10;
var myvariable = 90;
