I've been using the Roll Call external tool to take attendance in my class. I have the tool set in an assignment called "Attendance" within an assignment group also called "Attendance". Point values are 5 for each of 13 days, or 65 total. I've used the tool to take attendance in three class sessions, and would expect the gradebook to show students having 0, 5, 10, or 15 points in the Attendance Assignment Column, and 0, 33, 66, or 100% in the attendance group column. However, what shows is zero points and zero percent for all students.
How do I fix it so that students with 100% attendance show in the grade book as having 100% attendance, and so on?
