Tell us what’s happening:

Your code so far


// Setup
var myPlants = [
  { 
    type: "flowers",
    list: [
      "rose",
      "tulip",
      "dandelion"
    ]
  },
  {
    type: "trees",
    list: [
      "fir",
      "pine",
      "birch"
    ]
  }  
];

// Only change code below this line

var secondTree = myPlants[1].trees[1]; // Change this line

You’re on the right track…and I think it’s probably just a simple mistake. trees is actually the value of type and you need to access the value inside the list array. Look carefully at the code from the example in the lesson:

var ourPets = [
  {
    animalType: "cat",
    names: [
      "Meowzer",
      "Fluffy",
      "Kit-Cat"
    ]
  },
  {
    animalType: "dog",
    names: [
      "Spot",
      "Bowser",
      "Frankie"
    ]
  }
];
ourPets[0].names[1]; // "Fluffy"
ourPets[1].names[0]; // "Spot"

You’ll see here that you access ‘Fluffy’ by names[1] instead of dog or animalType. So to solve this one, you need to access the second tree by list[1] instead of trees.

Hope that makes sense! :slight_smile:
