Do... While Loop (What is the secret password?) - variable declaration not working.

The program tells me I need to declare the 'secret' variable before the loop, and I did. Tried these two declarations and both failed:

var secret; and var secret = ' ';

script.js 
var secret = ' ';
do {
var secret = prompt("What is the secret password?");
} while ( secret !== "sesame" ) 
document.write("You know the secret password. Welcome.");

You're using the var declaration twice. You'll want to remove it from the 3rd line of your JS, so it's just:

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