How can I solve this issue or turn this checkout off? Thanks for help.

`// button required to use
function createContact(firstName) {
this.firstName = firstName;
//, lastName, phoneNumber, email
// this.lastName = lastName;
// this.phoneNumber = phoneNumber;
// this.email = email;
}

var sampleContact = {
firstName: "Bill",
lastName: "Door",
phoneNumber: "01 294 323 434",
email: "billdoor@microsoft.com"
}

//onload sample contact
function showSampleContact() {
document.getElementById('firstName').innerHTML = sampleContact.firstName;
document.getElementById('lastName').innerHTML = sampleContact.lastName;
document.getElementById('phoneNumber').innerHTML = sampleContact.phoneNumber;
document.getElementById('email').innerHTML = sampleContact.email;
}

document.write(sampleContact.firstName)`
