Why is my code not working?

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

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

function getStudentReport ( 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('Enter a name or type quit to exit');
  if(search === null || search.toLowerCase() === 'quit') {
 break ;
  }
for (var i = 0; i < students.length; i += 1) {
  student = students[i];
  if(student.name === search) {
    message = getStudentReport( student );
    print(message);
  }

}
}
