Hello!

Just assign to the greeting variable, the genericGreet function using apply. The arguments are andrew (without quotation marks for it is a variable/object), and args1 which is the array. 

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

Your code looks good but you want to replace greeting with genericGreet

  var andrew = {
    name: "Andrew"

  }

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

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