In the task you're asked to use a while loop, not a do-while loop. Also, I'm not sure why you have the word "while" written twice. You also haven't declared index, and when using numbers in your while loop, you must drop "let" or else the compiler will think you're attempting to redeclare it.

I think you should re-watch the previous video and try tackling this again. Clean up your code, and try again. If you need help, then post in this thread again and I'll assist you.
