Instructor created a column for an assignment called Webinar. Grades entered incorrectly manually using "Simple Weighted Means" provide the correct number of points in the Max Grade column (710 points). When the instructor changes to "Sum of Grades" to match all the other grade categories the total points change to 50 less - 660 points in the max grade column.
we are using 1.9.8 Build 20100512
How can I get the sum of grades to be used and get the correct total?
