I am doing what the message below indicates (I use a for active in the
scode) but I am watching this discussion because I now need to produce
separate lists of how many were cancelled, ordered, died or merged and who
paid what for them....All lists separate by type, and by date.  Just a
running total won't be enough, so plan bigger.
