If you have multiple scheduled event modules or are using other types of modules (e.g., Assessment, Assignment, Document, etc.) along with a scheduled event module, you will need to ensure that the percentages you list do not exceed the total 100% for the course. If you accidentally exceed 100%, you’ll be greeted with the below message once you try to submit the course for publishing approval.
If you see this message, simply check your modules, and see where the percentage needs to be adjusted. Please note that you cannot move forward with submitting the course for publishing approval until the percentage has been corrected. You can tell this is the case because the “Next Visibility and Setting” option will not show up.
Once you correct the percentages, you will be able to move forward.
