Close Paul, but you are kind of on the right track.
Any record of change needs to show the Hive ID, a date on which the change occurred, and the changed value so that over time we can show the history of activities of the Hive.
Yes, I'll cop one on the chin for the stuff up regarding bodies. I had changed the Desc value because it occurred to me that during a 12 month period hive bodies may be added or removed during that time. I had a long long fathers day lunch with my family, before coming home to post the workbook.
