Hello Ashok.

You are prompting the question 2 times in your code, that is not need.

You basically need to prompt for the secret var in the "do" part, while the "while" part should now only reduced to checking that the password is different from "sesame". I would go like this:

do { secret } while (secret != "sesame");

So inside "do" we call the prompt and the question to the user, and while keeps checking the condition.

Please note that first and last line of code haven't been touched and should still maintain their default values.

Let me know if clear please.
