My code isn't running the prompts. What gives?

/* Quiz: Ask 5 questions, keep track of the number of questions answered correctly, provide results with how many questions they got right and give player a ranking */
/*5 Star Wars questions, stored in separate variables */
var questionOne = prompt("What is the name of Han Solo\'s furry friend?");
var questionTwo = prompt("What is the last name of Luke?");
var questionThree = prompt("What is the name of the dark side\'s secret weapon?");
var questionFour = prompt("What is the name of Luke\'s father?");
var questionFive = prompt("What is the first name of the mysterious man Han solo and everyone else visits?");

//Contain correct answers and count each correct answer as a point/

if (questionOne === 'Chewbacca') {
    var answerOne = 1;
}

//Compare points earned and give a score/

if (answerOne + answerTwo + answerThree + answerFour + answerFive == 5) {
    document.write('Congrats, you have earned the Gold Star!')
}
