re-write code using do while loop

it gives me a parse error . what is wrong here ? and also is there a simple way i can do this other than this...i just used the method in the video ...but honestly i don't understand why we have to write it in this complicated way using a do while , when we can just do it while...

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.");

var correctSecret =false; 
var secretCount= 0;

do { 
  secret = prompt ( "what is the secret password?");
    secretCount +=1 ;
  if (secret == "sesame") { 
   correctSecret = true; 
  } 

} while ( !correctSecret ) 
  document.write ( " you know the secret passowrd. welcome."; 
                  document.write( " it took you" + secretCount + "to guess the correct password" + secret);

Your code is good, once you add the ')' that Yonatan Arbel pointed out. Just delete or comment out the code that was provided when you opened the exercise. 

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.");

you just miss one parentheses at the "document.write" ( document.write ( " you know the secret passowrd. welcome.";

NO it still doesn't work . It says " bummer . use the prompt () method only once inside the loop. and define var above the loop " . I just don't get it
