Not showing any errors but also not working

I have written the code just like the instructor showed but when I run it shows a prompt but nothing works when entered into it. There are no errors being thrown either. Is there something I am missing in the code? I appreciate any help you can give me.

var message = "";
var student;
var search;

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

function getStudentReport( student ) {
    var report = "<h2>Name: " + student.name + "</h2>";
    report += "<p>Track: " + student.track + "</p>";
    report += "<p>Achievements: " + student.achievements + "</p>";
    report += "<p>Points: " + student.points + "</p>";
    return report;
}

while (true) {
  search = prompt("Seach for a student. 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);
   }
  }
}

Here's a few hints:

  • always use Markdown formatting when posting code
  • this code requires an array of "students" to work, but nothing by that name is defined here
  • a single "=" is an assignment operator, so the one in the "if" statement sets "search" to null
  • when invoking a method (such as "toLowerCase") you must put parentheses after the method name
  • when the other issues are fixed, remember that the browser will only render after you enter "quit"

Thank you Steven! I didn't even see those mistakes :) And also thanks for the tip about Markdown formatting, I'll be sure to use that from now on.
