When adding an assignment to more than one classes Gradebook at the same time, it won't let me save. Why?
When adding assignments to multiple Gradebooks at once, the Assignment type must be already included in all of the Gradebooks. If you are getting an error, double check your Gradebook setup for all section and make sure the assignment type you selected is included.
In order to do this open the Gradebooks and follow these steps:
Click Edit Setup
Next to the marking period click Edit
Select the Assignment type
Once the Assignment type is in all Gradebooks, you should be able to add your assignment to the gradebooks.
