        "firstName": "Akira",
        "lastName": "Laine",
        "number": "0543236543",
        "likes": ["Pizza", "Coding", "Brownie Points"]
        "firstName": "Harry",
        "lastName": "Potter",
        "number": "0994372684",
        "likes": ["Hogwarts", "Magic", "Hagrid"]
        "firstName": "Sherlock",

        "likes": ["JavaScript", "Gaming", "Foxes"]

function lookUpProfile(name, prop){
// Only change code below this line
for (var i=0;i<contacts.length;i++){
  if (contacts[i].firstName==firstName){
    if (contacts[i].hasOwnProperty(prop)){
      return contacts[i][prop];
      return "No such property";
    return "No such contact";

// Change these values to test your function
lookUpProfile("Akira", "likes");

hi @Wood-Cube

Its this line here:

if (contacts[i].firstName==firstName)

try replacing with:

if (contacts[i].firstName==name)

You want to be comparing the firstName value in the array with the name value brought in by the function, not itself.

Let me know how it goes!
