Hello again, @kmather ...
When you cross-list two courses, you need to first log in to the "child" course. This is where you will tell Canvas that you want to cross-list with the "parent" course. So, using the Guide that I provided to cross-list, sign in to the "child" course. Then, go to "Settings" in the course, and then click on the "Sections" tab. You'll then click on the name of your section on that screen, and you should see a button to cross-list courses. On the pop-up window that opens, you'll enter in the course information from your "parent" course. After you cross-list the two courses together, you can then log in to your "parent" course, and you should see enrollments from both courses in the "People" tab. If you need to cross-list another course with these two, repeat the above steps...logging in to that "child" course and cross-list it with the "parent" course.
I hope this additional information will be of help to you.
