do..while challenge

Hello, I'm stuck in this coding challenge. I looked back at the video but am still confused about the solution. I keep getting... "You only need to call the prompt() method once, and only inside the loop. Hint: Declare the secret variable before the loop."

Please Help...thanks!!

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

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

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

That's a pretty good hint.

It's trying to tell you that the top line should just be "var secret;" to declare the variable but not assign it yet. Then there will be only one call to prompt (the one inside the loop).

Also, it's a "best practice" to put a semicolon at the end of the while line.
