Describe your issue in detail here.

  **Your code so far**
// Setup
const contacts = [
  firstName: "Akira",
  lastName: "Laine",
  number: "0543236543",
  likes: ["Pizza", "Coding", "Brownie Points"],
  firstName: "Harry",
  lastName: "Potter",
  number: "0994372684",
  likes: ["Hogwarts", "Magic", "Hagrid"],
  firstName: "Sherlock",
  lastName: "Holmes",
  number: "0487345643",
  likes: ["Intriguing Cases", "Violin"],
  firstName: "Kristian",
  lastName: "Vos",
  number: "unknown",
  likes: ["JavaScript", "Gaming", "Foxes"],

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

// Only change code above this line

lookUpProfile("Akira", "likes");

This is a tough one.

Can someone please tell me where I am wrong?

How did this get in?

The handler of the first name should be the parameter defined in the function ‘name’, not ‘firstname’.
