Setting the "Greeting" Variable challenge

Can someone please take a look at my code here and let me know where I am missing in trying to set up the Greeting variable. Much appreciated. Thanks

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

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

Your variable "greeting" is wrong. Simply remove the ".greet" :)

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

Thanks Bryan. How about this last challenge in the prototypes section where they want us to set the prototype's wheels to 4. Here is my code:

  wheels = new Car (4);

Like so: 

function Car(model) {
    this.model = model;
        Car.prototype = carPrototype;
        Car.prototype.wheels = 4;
      }

After setting "Car.prototype" to equal the object "carPrototype", the last line creates a new key of "wheels" and gives it the value of 4, inserting it into the object.

This is probably the most confusing part of JavaScript to get a grip on, so do some Googling and rewatch the videos :)
