Does anyone see anything wrong with this code? Thanks -

Hey everyone -

For this video - when I preview my code and type search for an item like "milk" - nothing comes up. Just a blank browser.

Can you see what's wrong with my code? Thanks in advance - 

var inStock = [ 'apples', 'eggs', 'milk', 'cookies', 'cheese', 'bread', 'lettuce', 'carrot', 'broccoli', 'pizza', 'potato', 'crackers', 'onion', 'tofu', 'frozen dinner', 'cucumber'];
var search;

function print(message) {
  document.write( '<p>' + message + '</p>');
}

while (true) {
        search = prompt("Search for a product in our store. Type 'list' to show all of our produce and 'quit' to exit."); 
        search = search.toLowerCase();
      if (search === "quit") {
          break;
          } else if (search === "list") {
            print( inStock.join(', '));

          } else { 
            if( inStock.indexof( search ) > -1 ) {
              print("Yes, we have " + search + " in the store." ) } else {
          print(search + " is not in stock.")
          }
        }
      }

You have a typo on your indexOf(). you have it spelled in all lowercase. It should be in camel case

if (inStock.indexOf(search) > -1) {
  print("Yes, we have " + search + " in the store.")
} else {
  print(search + " is not in stock.")
}

What is my error here? 

var inStock = [ 'apples', 'eggs', 'milk', 'cookies', 'cheese', 'bread', 'lettuce', 'carrot', 'broccoli', 'pizza', 'potato', 'crackers', 'onion', 'tofu', 'frozen dinner', 'cucumber'];
var search;

function print(message) {
  document.write( '<p>' + message + '</p>');
}

while (true) {
  search = prompt("Search for a product in our store. Type 'list' to show all of the produce and 'quit' to exit");
  search = search.toLowerCase();
  if ( search === 'quit') {
    break;
  } else if ( search === 'list' ) {
    print( inStock.join(', ') );
  } else {
    if (inStock.indexOf( search ) > -1 ) {
      print('Yes we have ' + search + 'in the store');
    } else {
      print( search + 'is not in stock');
    }
}

You are missing a closing curly brace on your while loop. Also, you are missing a space in your 'Yes we have ' + search + 'in the store'. There should be a space before in

var inStock = ['apples', 'eggs', 'milk', 'cookies', 'cheese', 'bread', 'lettuce', 'carrot', 'broccoli', 'pizza', 'potato', 'crackers', 'onion', 'tofu', 'frozen dinner', 'cucumber'];
var search;

function print(message) {
  document.write('<p>' + message + '</p>');
}

while (true) {
  search = prompt("Search for a product in our store. Type 'list' to show all of the produce and 'quit' to exit");
  search = search.toLowerCase();
  if (search === 'quit') {
    break;
  } else if (search === 'list') {
    print(inStock.join(', '));
  } else {
    if (inStock.indexOf(search) > -1) {
      print('Yes we have ' + search + ' in the store');
    } else {
      print(search + 'is not in stock');
    }
  }
}
