var questions = [ ["What color is an Apple", "Red"], ["What color is an Blueberry", "Blue"], ["What color is an Pumpkin", "Orange"] ]; var correctAnswer = 0; var question; var answer; var response; var html; function print(message) { document.write(message); }

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

html= "You got " + correctAnswer + " question(s) right."; print(html);

Hi Adam!

Code

Wrap your code with 3 backticks (```) on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting.

      ```html
      <p>This is code!</p>
      ```

The problem is here:

response = parseInt(prompt(question));

You are givin a string (e.g. Red) as an answer. Now, parseInt will parse an integer out of it. Remove parseInt and it works. Though you might need some improvement still. Like put all your answers in CAPITAL letters in the questions array. Then use toUpperCase() on your prompt. Note it has different syntax than parseInt: string.toUpperCase()
