Can anyone give me some tips to fix my code? :-)

// 5 questions 
var question1 = prompt('How many fingers do you have in one hand?'); 
var question2 = prompt('How many fingers do you have in two hands?'); 
var question3 = prompt('How many eyes do you have?');
 var question4 = prompt('how many days have a week?'); 
var question5 = prompt('What is the color of the sky?');

// Answers and Scores 
var answer1 = 5; 
var answer2 = 10; 
var answer3 = 2; 
var answer4 = 7; 
var answer5 = 'blue';

if (parseInt.question1 === answer1) 
{ 
var score1 = 1; 
} else { 
score1 = 0; 
}
 if (parseInt.question2 === answer2)
 { 
var score2 = 1;
 } else {
 score2 = 0;
 }
 if (parseInt.question3 === answer3) {
 var score3 = 1;
 } else {
 score3 = 0; 
} 
if (parseInt.question4 === answer4) {
 var score4 = 1; 
} else {
 score4 = 0; 
} if (question5 === answer5) { 
var score5 = 1; 
}  else {
 score5 = 0;
 }

/* We'll let the player know how many questions did he/she got right.
 And we'll show that using document.write() */
 var totalScore = score1 + score2 + score3 + score4 + score5; 
document.write("You've got " + totalScore + " questions right");

//rank the players and show the rewards 
var goldCrown = 5; 
var silverCrown = 3; 
var silverCrownToo = 4; 
var bronzeCrown = 1; 
var bronzeCrownToo = 2;

if (totalScore === goldCrown) { 
alert('You have earned the Golden Crown!'); 
} else if (totalScore === silverCrown || totalScore === silverCrownToo) {
 alert('You have earned the Silver Crown!');
 } else if (totalScore === bronzeCrown || totalScore === bronzeCrownToo) {
 alert('You have earned the Bronze Crown!'); 
} else { alert('You should try it again!'); }
