You didn't say if you want the sums/counts for a time period across all dates or per date. Either way, I would have thought a calculated control on the report would suffice, without extra queries. Can't say where it would go though, because the date span of the totals isn't clear. A bigger problem at the moment, I think, is that for 8:00 AM, which column would it go in - the first or second? They both cannot be exactly 08:00:00.
The more we hear silence, the more we begin to think about our value in this universe.
