Why can I not get an output on my browser? All the other lines work but I can't get person.skills.length on the screen

var person = {

    name : "Jones",
    country : "Brazil",
    age : 15
    skills : ["Javascript", "HTML", "CSS"]
};

function print(message) {

    var div = document.getElementById('output');
    div.innerHTML = message;
}

var message = "<p> My name is " + person.name + "</p>";
message += "<p> I am Originally from " + person.country + "</p>";
message += "<p> I am " + person.age + " years of age </p>";
person.age += 1;
message += "<p> But I wish I was " + person.age + "</p>";
person.name = "Marcus";
message += "<p> And I wish my name was " + person.name + "</p>"; 
message += "<p> I have " + person.skills.length + " skills </p>";
print(message);

Hey Ken,

You have a typo here:

var person = {

    name : "Jones",
    country : "Brazil",
    age : 15 //There should be a comma here 
    skills : ["Javascript", "HTML", "CSS"]
};

Fix that and it should work.

You forgot to include a comma after your age.

var person = {

name : "Jones",
country : "Brazil",
age : 15,
skills : ["Javascript", "HTML", "CSS"]

};
