Code challenge loops do... while

This is my code and I don't understad what is wrong:

Bummer said: You only need to call the prompt() method once, and only inside the loop. Hint: Declare the secret variable before the loop.

BUT I DID, right?

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


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

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

No, you don't just call it once. You call it once at the start of the solution and then a second time inside the loop. If you remove the call to the prompt method at the start like this:

var secret; // Removed "prompt" call
var answer = false;


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

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

Then your solution will pass.
