Problem with a Challenge

Here is a challenge that is getting me:

Modify this object so it uses two properties firstName and lastName and remove their variable declarations from the fullName method. Don't do anything to theconsole.log() call right now.

var contact = {
  fullName: function() {
    var firstName = "Andrew";
    var lastName = "Chalkley";
    console.log(firstName + " " + lastName);
  }
}

This is what I thought they were looking for:

var contact = {
firstName = "Andrew",
lastName = "Chalkley",
fullName: function() {

    console.log(firstName + " " + lastName);
  }
}

But I got a parsing error. Now I’ve looked at it so long I not even sure I know what they are asking for.

object.js 
var contact = {
  fullName: function() {
    var firstName = "Andrew";
    var lastName = "Chalkley";
    console.log(firstName + " " + lastName);
  }
}

Hi Doug,

You're close. In an object literal, you need to use a colon (:) to assign properties instead of =.
