Can anyone tell me what's possibly wrong in this code???

var message = '';
var student;
var search;

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;
}

function getStudentName( student ) {

  var report = '<h2>Student: ' + student.name + '</h2>';
  report += '<p>Track: ' + student.track + '</p>';
  report += '<p>Points: ' + student.points + '</p>';
  report += '<p>Achievements: ' + student.achievements + '</p>';
  return report;
}

while (true) {
  search = prompt("Search the students records: as for example, type [jody] to get his info or       type quit to quit the search");

  if (search === null || search.toLowerCase() === "quit") {
  break;
  }

for (var i = 0; i < students.length; i += 1) {
  student = students[i];
  if( student.name === search){
  message = getStudentName( student );
  print(message);
    }
  }
}
