Treehouse TeacherAbsolutely nothing is wrong with it. If I take the code that you posted at the top, and paste it in to the current charge method, the challenge passes! However, if I try to use the code posted in the second bit, it fails because it explicitly wants you to use the unary ++ operator. The question is why you aren't passing the challenge. My best suggestion is to close the browser and reopen it, and start the challenge again. Paste the code you have in the top section into the current charge function and press "check work". If it's still failing you might have to contact support. Happy coding!
