I have a list of classes. They are numbered (primary key) and have an associated class date. There is one class per date. I also have a list of registrants. They link the registrant name to the assigned class number, date and instructor. I can group and view my registrant list by class number and add registrants in this view. But, when I group registrants by class date I find I cannot enter new registrants - date appears to be a calculated field. It would be easier for us to see the “July 6th, 2021” class in a grouped view and add registrants that way. Any suggestions? Thank you in advance.
