Crosstab query totals

My sql
TRANSFORM Count(QDailyWheplingReport2.[NEST #]) AS [The Value]
SELECT QDailyWheplingReport2.[WHELPING DATE],
Count(QDailyWheplingReport2.[NEST #]) AS [Total Of NEST #]
FROM QDailyWheplingReport2
GROUP BY QDailyWheplingReport2.[WHELPING DATE]
PIVOT QDailyWheplingReport2.[SHED #];


I am trying to understand how the total works.
I have columns which are shed numbers from 1 to 50
The rows are dates, the days that litters were born.
The nests are the count of each litter, (the value)
At the top of the query data view is a total of the nests in each shed,
and as the dates or rows accumulate and liters are born each day, the
total goes down as the nest's column count goes up.

I would like a sum of all the days count, (Excluding the total at the top)
so I know how many litters were born in that shed.

My problem is when I make a report off this query and bring down the field
list
There is a [Whelping Date] field, a [Total Of NEST #] field, and all the
[Shed] fields
when I put the shed field in the report and view the report this total is at
the top and
all the days counts are there, BUT

How do I access the total to subtract it from my column sum, when I sum the
shed field?

Thanks for any suggestions
