Yoo waddup Oliver, sometimes it's best to go over the video to see what you did wrong. There are some things wrong with the following answer.

You do not need an if statement to check whether it should keep looping or not. The "while" will do that for us.

When you call a do while loop, it isn't two different statements.

First make it so we have a variable to work with.

var secret;

Then create your do while loop so that the prompt will at least be asked the first them whether the loop is false or not.

do {
  secret = prompt("What is the secret password?");  
} while ( secret !== "sesame" );

Then have this outside of your loop because we don't want this to be repeated, rather we want this to be displayed once the do while loop is finished!

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