Stuck on this objects question.

Set the 'greeting' variable, on line 29, by using the 'genericGreet' function in the context of 'andrew' with the array of arguments, 'args1'.

Im probably doing something wrong here:

<!DOCTYPE html>
<html lang="en">
  <head>
    <title> JavaScript Foundations: Objects</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Objects: Call and Apply</h2>
    <script>
      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;
      //what I came up with
      andrew.greeting.apply(andrew, args1);

    </script>
  </body>
</html>

      }

    <h1>JavaScript Foundations</h1>
    <h2>Objects: Call and Apply</h2>
    <script>
      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;
      andrew.greeting.apply(andrew, args1);

    </script>
  </body>
</html>

Never mind I got it. I just had to assign not call it like so:

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