Hi Andrian, you have written

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

but it wants you to set the greeting using the genericGreet function. As you can see that function takes two arguments...so it follows up by telling you to do that using "andrew" and "args1" so, what it wants is you to do this.

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