Perhaps I was not explicit enough in the hint I gave in your previous question:

In a "do...while" loop, the "do" comes before the code block, and the "while" comes after it.

The "code block" is the part enclosed in braces {}; The "while" will go after that section. Inside the code block, you will still call the "prompt" function and assign it to the "secret" variable.

Also, one reason to change the loop type is so you will only need to call "prompt" in one place.

So when you have properly constructed the loop, you will no longer need to call "prompt" before the loop starts. All you'll need to keep of the first line is the declaration of the variable "secret", but you won't need to assign it yet.
