Don't worry, you're question has been submitted! Once you submit a quesiton it won't be posted to the site, but it will be sent to your instructor for review. If your instructor selects your question to answer in their next Office Hours it will then be posted with their answer for everyone to see! You will receive a notification once it gets posted.
If you are looking for a more immediate answer you can always discuss it with your classmates. Utilize the discussions to gain more insight into the class, your instructor, and answer questions you have about the class material.
