List unchecked from checkbox
I was wondering if someone would be able to give me some insight on how (or even if) I can create a list based on unchecked items in a check box. My final goal is the have a list of uncheck between two checkboxes. I am creating a course list that has one checkbox for courses completed, one for courses currently enrolled and would like one populated with courses still need to be taken. Any help would be hugely appreciated. Thanks!
