Hey Marc, what issues are you having with the code? I just ran it in my console and it asked me for a password, if I enter 'sesmame', I get notified I know the password. What else would you like the code to do?

Hi Marc,

You're really close to solving the challenge.

I tried you're code in the challenge and got the error

ReferenceError: Strict mode forbids implicit creation of global property 'secret'

Because the challenge is in strict mode you need to declare the variable secret.

Here's some info on strictmode

The variable must be declared outside of the function and doesn't need to be given any kind of value yet.

let secret;
do {
    secret = prompt("What is the secret password?");
    // code to run
  }
  while ( secret !== 'sesame') {
    alert("You know the secret password. Welcome!") };

Hope that helps!
