Basic JavaScript: Profile Lookup error :(

Guys Hello,

What is wrong about my code down below, I cannot find any syntax errors right now?

//Setup
var 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

for (var i = 0; i < contacts.length; i++){
    if (contacts[i].firstName === firstName) {
        if (contacts[i].hasOwnProperty(prop)) {
            return contacts[i][prop];
        } else {
            return "No such property";
        }
    }
}
return "No such contact";

// Only change code above this line
}


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

firstName looks undefined.

In the if statement above you are comparing to a variable ‘firstName’ but I think you meant to compare to the input parameter called ‘name’ ?
