There are a few problems with your code. If you try to execute your code and examine the console output, or run your code through a JS linter (such as JSHint), it will quickly reveal some problems for you - give this a try.

Hint: You're missing a semicolon.

EDIT: After properly formatting your code, it seems the missing semicolon is not the problem (though you should still put one after your prompt assignment statement, if just to be consistent), and Chyno has beat me to the answer.

Yes. Try adding single or double quotations when using the

if (search === "quit") and the if (search === "list")

it should work after that. Also when adding a string plus a variable to a message remember to add spaces

if(inStock.indexOf(search) > -1) { print("yes,we have" + search + "item in the store.");

if(inStock.indexOf(search) > -1) { print("yes, we have " + search + " item in the store."); }

Good luck :)

you have your conditional statemenst searching for variables labeled quit and list rather then strings of "quit" and "list". Once you change those. It should work just fine.

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 the 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 + "item in the store.");     
    }
        else {
        print("sorry,we dont have "+ search + "in our store.");
        }
      }
}

I hope this helps.
