My code is not tracking the correct answers, help please!

I can't seem to really wrap my head around whats wrong with this one. I tried really hard to get it 100% correct on my own and got pretty close, but I was not able to get the correct var to store and alert the amount of answers that were correct. I even followed through the solution video a number of times with this one to see whats wrong with it, but it still returns 0 right every time!

Hi Paul,

You just had an error in your answer variable in the for loop. You put [i,1] instead of [i][1] like so:

for (var i = 0; i < questions.length; i += 1) {

     question = questions[i][0];
     //changed to questions[i][1] correct notation
     answer = questions[i][1];
     response = parseInt(prompt(question));

   if (response === answer) {
      correct += 1;
   }       
}

I knew it was going to be something subtle like that. Thanks so much - headache gone.
