Hi @BarbaraSage,
It sounds like you are trying to manually enter a value into one of the columns that exists on the far-right side of the "Grades" table. Is that where you are and what you are trying to do?
The far-right side of the "Grades" table is for each of the assignment groups that exist in the "Assignments" area of the course. Each of these columns is automatically populated as grades are entered/released for the individual gradeable items that are in the assignment group.
The two support articles provided below should be able to help you.
- How do I use the Gradebook? - Instructure Community - 701 (the area I am referring to is the final section of the support article named "View Assignment Groups and Total Column")
- How do I enter and edit grades in the Gradebook? - Instructure Community - 724
If what I have described is not accurate, please provide a picture (making sure to not include any private/privileged names) of what you are referring to so that I or someone else can help you?
-Doug
