As with several Workspaces in this series I CANNOT get the preview to work properly. (Tried cache clearing, restarting.)

No matter how many times I review the code I cannot get it to run in preview properly.

HTML:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Search the Store</title> <link rel="stylesheet" href="css/styles.css"> </head> <body> <h1>Search the Store</h1> <script src="js/search.js"></script> </body> </html>

JAVASCRIPT:

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 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.'); }
}

Seth Kroger is correct. You're missing a closing } for the while loop. Look at my example below.

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 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're missing this closing bracket

Not sure how that happened but I will say that adding space in your code helps to read it better. Therefore, possibly making it easier to catch such syntax errors.

Looks like you're missing the closing brace on the while loop.
