Hello @MargaretAdamek
Thank you for contacting the Canvas Community. It sounds like you are experiencing an issue with posting or finalizing grades. However, we need more details in order to help and provide a solution to you. Is the problem within Canvas specifically or do you need help finalizing and submitting grades to your school or institution? If so, you should reach out to the school directly as each school has their own methods of finalizing grades from Canvas. If you have an issue with the gradebook, this guide may help:
