Error Message

I have a new class with 6 sections (plus a "test" section that I used to experiment this summer). I had my kids respond to a graded discussion in class yesterday. The discussion worked fine. Kids responded. The discussion shows up in my "to do" list to grade. I click on the link to grade it. But then I get the message "Sorry, there are either no active students in the course or none are gradable by you." I went back and checked. I was only listed as the teacher for 1 section. So I added myself to all of the sections. But now when I click on the link (to be able to grade) I still get the same message. Any ideas of what I have done wrong?
