Well let's try with a hint. :smiley: Ok so you start by asking the user for a password, and you set their response into the variable secret. Then you say while secret is not equal to sesame. Let's imagine for a moment that I entered "Hello" because I didn't know the password. Your code will loop endlessly. Because "Hello" will never be equal to "sesame", and you've never given me a chance to try again. Somewhere in there you need to give the user an opportunity to try another word! Good luck! :sparkles:

edited for additional note

Someone else pointed out something earlier that I missed as well. You're trying to use echo, which isn't a valid way to output information with JavaScript. You can use document.write to write to the document, console.log to write to the console, innerHTML to write inside an HTML element, or use an alert to display a popup with information to the user.
