your really close on this, just switch the empty var secret with the var secret the equals the prompt. you want the prompt to run inside the while loop. and delete the var sesame the you want the input from the var secret to equal sesame not a new var.

Hi Jacob...

I wrote this:

while (secret !== "sesame"){

   var secret = prompt("What is the secret password?");

}
document.write("You know the secret password. Welcome.");

I have to strictly use the !==

It gives me this error:

Bummer! Don't use the var keyword inside the loop. You only need to declare the secret variable once, at the beginning of the script.

I just edited your response to view your code properly.

okay so first before we declare the loop we need a var called secret. then inside the loop we want to say while the input from the prompt does not say sesame loop again. So with what you have is really close the only thing you need to do is set the var secret as an empty var outside of the loop, then inside the loop have the var secret equal the prompt. remember outside you need to state var secret; inside the loop all you need to secret.

Ah! Ok now I understood!

I have to declare the var outside the loop, than only "call" it inside, without declaring it.... i confused it with a function.

Thank you Jacob, very helpful!
