Hi Zachary, I assume your code isn't running? It looks like you have some extra lines of code in your script. The basic structure of the do...while loop is: 

do {
  //some stuff here
} while (//this condition is true)

So all you need to do is declare your variable outside of the loop, then set its value inside the 'do' part of the loop, and then have your condition (secret !== "sesame") inside the parentheses, before the document.write() statement.

Hope that helps!
