I'm not getting the the counter to add to the correctAnswers. Help please.

Code:

var questions = [ ["What's my name?", "CHRIS"], ["What's up?", "THE SKY"], ["What's good?", "NOT BAD"] ];

var correctAnswers = 0; var question; var answer; var wrongAnswers = 0; var response; var html;

function print(message) { document.write(message); }

for ( i = 0; i < questions.length; i +=1 ) { question = questions[i][0]; answer = questions[i][1]; response = parseInt(prompt(question));

if (response.toUpperCase === answer) { correctAnswers += 1; } else { wrongAnswers += 1; } }

html = [["You got " + correctAnswers + " questions right."] + " " + ["You got " + wrongAnswers + " questions wrong."] ]; print(html);

Oh yeah, youre missing 2 parenthesis after the toUpperCase function, like this:

var questions = [ ["What's my name?", "CHRIS"], ["What's up?", "THE SKY"], ["What's good?", "NOT BAD"] ];

var correctAnswers = 0; 
var question; 
var answer; 
var wrongAnswers = 0; 
var response; 
var html;


function print(message) {
  document.write(message);
}


for ( i = 0; i < questions.length; i +=1 ) { 
  question = questions[i][0]; 
  answer = questions[i][1]; 
  //alert(answer);
  response = prompt(question);
  //alert("response = " + response);

  if (response.toUpperCase() === answer) { 
    correctAnswers += 1; 
  } else { 
    wrongAnswers += 1; 
  } 
}


html = [["You got " + correctAnswers + " questions right."] + " " + ["You got " + wrongAnswers + " questions wrong."] ]; print(html);

I suggest using alerts to see what your code is doing when you are not getting the desire result.

Hope it helps.

In this line:

          response = parseInt(prompt(question));

It seems you are trying to get an integer, but your answers are strings.

Just remove the parseInt and its braces.

          response = prompt(question);

Didnt test it but i think it should work.

Thanks. But that doesn't seem to help. The counter still doesn't work.
