First, I had not used a CrossTab in quite a while. So, my memory about certain aspects of it were "gone". The problem was arising from the "Display Column" that did not have a Table column or Function. Not sure how that happened but that was the problem. I do think that a Table column was typed in it (not using the "Remove" button) but that did not work. As soon so I used the "Remove" button and used the "Add" button it worked.
