Try this:

var secret;

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

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

I hope this will help you :-)

:point_right: You are missing a closing brace for your do...while loop.

The open brace following the do should be matched by a closing brace right before the while. This would be in addition to the closing brace of the if block which is there now.

However, even when repaired, this code needs some additional work to pass the challenge:

  • the correct answer must be "sesame"
  • the gettingPassword routine should be removed
  • the secretAnswer can be initialized with an empty string ("")
  • the return value of the prompt should be assigned to secretAnswer (not secret)

Henrik's condensed version would also pass the challenge.
