HEEEELP! I cannot pass the challenge!

Can anyone please help me out here?

I am testing this on chrome console and I do get the desired result. But in the challenge is not accepted. Here is my answer:

var genericGreet = function(name, mood) {
        name = name || "you";
        mood = mood || "good";
        return "Hello " + name + ", my name is " + this.name +
          " and I am in a " + mood + " mood!";
      };

   var andrew = {
        name: "Andrew"
      }

     var args1 = ["Michael", "awesome", ":)"];

      var greeting = genericGreet;
      genericGreet.apply(andrew, args1);

You should combine last 2 lines. You call genericGreet with context of andrew and array with arguments "arg1", then you store result in the variable greeting:

var greeting = genericGreet.apply(andrew, args1);

Hi Christina:

Try calling it through the greeting variable you declared, so 

greeting.apply(andrew, args1);

I believe that should make the test pass.
