Can someone help with this do while loop assignment. I can't figure it out

I can't figure out why this is wrong and what is the correct way to turn the commands into a do while loop

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

The do/while loop is written like this

do {
    // Code to execute
}
while ( 
     // Statement that is true
);

You can read about it on W3schools

Place the following code in your script.js and it should work:

var secret;  //<-- declare variable outside of loop to save on memory

do {
  secret = prompt("what is the password?"); //<-- set secret to equal a prompt asking for the password
} while (secret !== "sesame") //<-- as long as secret isn't equal to "sesame" the code block above will continue to execute
    if (secret == "sesame") { //<-- once loop is ended by secret being equal to sesame this conditional checks for a match
        alert("you know the password"); //<-- if secret in fact is equal to sesame then here I used an alert but you can use what you'd like to give message
    }
