It is not the pivot table itself (per se) that I am trying to group. Rather, I am trying to group the column field (comprised of dates, none of which are blanks as suggested by the previous link). I am absolutely sure this is possible, as I have both manually achieved this (right click a cell in the field and selected 'Group'), as well as through a very simple vba script (see code at bottom of original post). I have been trying to follow the documentation at MSDN documentation with no success.
