Which class are you enrolled in? You posted your message in the “General Discussions” forum, it’s not associated with any specific course.

Please move your thread to the correct forum. For this you can use the “pencil” icon next to the thread title.

Note: The grader always tests your code using different test than are built into the notebook. Your code must work for any situation.

Note also that if you rename your notebook, the grader will fail. This is because the grader always uses the default notebook name, regardless of what notebook you have open when you submit it for grading.
