JavaScript Methods 1 Challenge, task 3 of 4

Challenge is asking: "On about line 20, add the 'firstWord' variable to the beginning of the array 'saying'." My code:

      var spareWords = ["The","chimney","sweep's","dog"];
      var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"];
      var firstWord = spareWords.shift(); 
      spareWords.unshift("firstWord");
      var lastWord = spareWords.pop();
      sparewords.push("lastWord");

      //my solution:
      saying.unshift(firstWord);
      saying;

feedback from challenge:"Bummer! There's something wrong with your 'saying' array." I don't understand this.

 <script>
      var spareWords = ["The","chimney","sweep's","dog"];
      var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"];
      var firstWord =  spareWords.shift();
      spareWords.unshift("firstWord");
      var lastWord = spareWords.pop();
      spareWords.push("lastWord");
      saying.unshift(firstWord);
      saying;
    </script>

Now it works...

Your code is correct from what I can tell as I just passed with the same. I will paste what passed below so you may check. But think you may need a refresh and try again. I blame the gremlins for this one. Also I edited your post for correct markdown, if you click edit you can see how it is formatted now. 

    var spareWords = ["The","chimney","sweep's","dog"];
    var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"];
    var firstWord = spareWords.shift();
    var lastWord = spareWords.pop();
    saying.unshift(firstWord);
    saying;

Did you add the quotes to "firstWord"?

You don't need the quotes for a variable!!
