Unexpected identifier?

The unexpected identifier is on Line 27:

if questionSky.toUpperCase() === 'BLUE'

//five questions

var questionSky = prompt("What color is the sky?");
var questionGrass = prompt("What color is the grass?");
var questionPavement = prompt("What color is the pavement?");
var questionDwarves = prompt("How many dwarves are in Snow White?");
var questionStooges = prompt("How many stooges are there?");

//Keeping track which ones are correct

var QuestionsCorrect = 0;

if questionSky.toUpperCase() === 'BLUE' {  
  var QuestionsCorrect += 1; 
}


if questionGrass.toUpperCase() ===  'GREEN' { 
  var QuestionsCorrect += 1;
}

if questionPavement.toUpperCase() === 'BLACK' {
  var QuestionsCorrect += 1;

}

if parseInt(questionDwarves) === 7 {
  var QuestionsCorrect += 1;

}

if parseInt(questionStooges) === 3 {
    var QuestionsCorrect += 1;
}

//Alerting how many questions are correct

alert("Congrats, you got " + QuestionsCorrect + " questions correct!");

//Bestowing of the crowns

if QuestionsCorrect === 5 {
  document.write("You get a gold crown!"); 
}

else if QuestionsCorrect === 4 || QuestionsCorrect === 3 {
  document.write("You get a silver crown!");

}

else if QuestionsCorrect === 2 || QuestionsCorrect === 1 {
  document.write("You get a bronze crown!");

}

else QuestionsCorrect === 0 {
  document.write("You don't get a crown!");

}

I don't know what is wrong, I've been looking at this for quite a while. Thanks!

var questionsCorrect = 0;

if (questionSky.toUpperCase() === 'BLUE') {  
  questionsCorrect += 1; 
}
if (questionGrass.toUpperCase() === 'GREEN') { 
  questionsCorrect += 1;
...
}

Hi Dan, here's a couple of points to note:

  • JavaScript if conditions need to be surrounded with '(' and ')'
  • var questionsCorrect should be declared just once near the top .

Hope this helps.

There is a problem with your if statement, basic if statement is as follows:

if (condition) {
   //code 
}

Therefore, your if statements should be changed and also you already made the var QuestionCorrect at the top so there is no need to type var again.

if (questionSky.toUpperCase() === 'BLUE') {  
   QuestionsCorrect += 1; 
}

Hope this helps!
