Stuck on do/while problem

I keep getting an error saying to declare the variable secret before the loop runs but I thought I did exactly that:

var secret = "sesame"; var password; var correctPassword = false;

do{ var secret = prompt("What is the secret password?"); if (password === secret){ correctPassword = true; }

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

What am I missing here? I've been stuck on this for weeks!

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

Hi Michelle,

You just need to change it to a 'Do, While' loop. The define secret at the beginning is 'var secret;'. See below:

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

This worked for me; thanks again! As usual, I overthought the problem.

I ran your code on my local computer - it works fine. I think this may be a cache issue with the workspaces program - try running it locally using a program like brackets. It works fine.

Hey Steve, as you've said, no issue with the code. The issue is with passing the Challenge, where the 'prompt' should only be called once, not twice.

This passed for me, If you have any questions about the code I'd be happy to explain

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