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("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 = getStudentReport(student);
  print(message);
}

}

}
