If you're having a problem with a challenge not accepting your code, showing a confusing message, or if you’re not sure how to proceed to complete the challenge or project, you can access the Study Group Community and post your questions. It's a great opportunity to reach out to a global circle of learners and teachers who are always happy to help! (This can only be done by users who are 13+ years old).
Besides posting your questions on the Study Group, you can click on Report a problem on the right-hand side of the Hint. That will go into a dedicated system for challenge grader reports that will capture your code as well.
If you identify that your problem is an actual bug or glitch, please use the Report a problem button in the Help Center and send a Help request describing the steps you took and provide screenshots if possible.
