I can not for the life of me figure out what is the error in the follow Javescript code.

 

function main()

{

   var highScore;

   var lowScore;

   

   var numExams = 5;

   var examArray = [];

   

   for (ctr = 0; ctr < numExams; ctr++)

   {

       examArray[ctr] = Number(prompt("Enter the score for exam " + ctr));

   }

   

   highScore = examArray[0];

   lowScore = examArray[0];

   

   for (ctr = 0; ctr < numExams; ctr++)

   {

       if (examArray[ctr] > highScore)

       {

           highScore = examArray[ctr];

       }

       else

       {

           lowScore = examArray[ctr];

       }

   }

   console.log("High score is " + highScore);

   console.log("low score is " + lowScore);

}

main();
