This is the code we used in the last code challenge. After learning about do...while loops, don't you think this would work better in the do...while style? Re-write the code to use a do...while loop.

script.js 
var secret = prompt("What is the secret password?");
var count = 1;


do { secret !== "sesame" 
  secret = prompt("What is the secret password?");   
  count += 1;
   }
document.write("You know the secret password. Welcome.");

while (count <= 10);

This wouldn't be proper syntax, and there are a few other issues:

  • the "while" must come immediately after the brace ending the loop block
  • the test expression on the same line as "do" is not proper syntax
  • one advantage of a "do" loop is that only one call to "prompt" is needed
  • if the "while" only tests the count, it will keep asking even if the word is correct

Give it your best "good faith" try, and refer to the hints I gave above. If you still have trouble, start a fresh question and include your code in it.
