Javascript: Loops, arrays & Objects: The Student Record Search Challenge

Hi all,

This is driving me mad. I can't see where my code is going wrong. The while loop runs until 'quit' is typed in but when I type in a student name, e.g. 'Anthony' it doesn't display their student record upon quitting. No html is sent to the the outputDiv :- any experienced eyes see what's going on here for me please?

Thanks.

   name: 'Dave',

  }
];

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("What would you like to search for?");
  if (search === null || search.toLowerCase() === "quit") {
    break;
  }
  for (var i = 0; i < students.length ; i++ ) {
    student = students[i];
    if (student.name === search) {
        message = getStudentReport(student);
        print(message);
    }
  }
}

Aaaaaaah!!! I've just realised, instead of using my own array of students I'd created earlier, I was using Daves list. I've spent about an hour at this thinking my search terms were correct when they weren't.
