hi pman, Those numbers are monthly sales - a running total of the sales in the past 30ish days. a drop in the number of that magnitude would likely be caused by no sales on the day you checked (no stock perhaps), or it could simply be that there is a start to the count for the day, and you caught it at the beginning. Regardless, looking at the change in that number from one day to the next is meaningless if I understand correctly. Of interest is the number itself and then checking it again on a monthly basis.
