I am not sure how you will be able to use a select statement to exclude the data but you should be able to get the values you want by using a variable formula or a Running Total (my preferred method) and comparing it against your full record set.
group on inmate (ID preferrable so you do not group 2 people with the same name)
Sort by {Audit_Trail.DateStamp}
Create a Running Total as "OutCount"
Field to summarize = Inmate ID
Type of Summary=Distinct Count
Evaluate=Use a formula
{Audit_Trail.FieldName} = Temporary_Out and {Audit_Trail.BeforeValue}=0 and {Audit_Trail.DateStamp}: 02/04/2010 <= {?date param}
and
(next({table.inmateid})<>{table.inmateid}
or
(next({table.inmateid})={table.inmateid} and
next({Audit_Trail.DateStamp})>{?date param})
Reset=Never
Place thi sint he detail section and you should see it it count up once per inmate that was out on the date you enter for the param.
plac eit in the report footer for a total.
You can use it for suppressing names and also to subtract from your disticnt count of all to get a number that were 'in' vs. 'out'
Does this work?

{Audit_Trail.DateStamp}: 02/04/2010 <= {?date param} says it is not part of the formula. And why the date 02/04/2010?

sorry, that is what I get for a cut and paste  Embarrassed
Try this:
{Audit_Trail.FieldName} = Temporary_Out and {Audit_Trail.BeforeValue}=0 and {Audit_Trail.DateStamp} <= {?date param}
and
(next({table.inmateid})<>{table.inmateid}
or
(next({table.inmateid})={table.inmateid} and
next({Audit_Trail.DateStamp})>{?date param})
)

I would start to deconstruct the evaluate formula inthe RT and then re-run it each time to see if your values change to try and figure out where the problem is at.
Try the first set of conditions to see if they work:
{Audit_Trail.FieldName} = 'Temporary_Out' and {Audit_Trail.BeforeValue}=0 and {Audit_Trail.DateStamp} <= {?date param}
then try the next set.
Also change the setting from 'Exceptions for NUlls' to 'Default Values for Nulls'.
Does either part of the formula work 'correctly'?

Ok I played around with it. What worked was this:
{Audit_Trail.FieldName} = 'Temporary_Out' and {Audit_Trail.BeforeValue}=0 and {Audit_Trail.DateStamp} <= {?date param}
and then set in Reset On Change Field to {Audit_Trail.FieldName} and now I get the Number 1 for all <= date param
 
So now how do we limit it to between the time that the inmate was out{Audit_Trail.BeforeValue} and {Audit_Trail.AfterValue}

Do you have an inmate ID # in the table?

unless I misunderstand your data set you have to comapre it to the next row but also account for that there may not be a next row to 'close' that pair (meaning they are still out on furlough as of today).
Hence the use of the NEXT() function in the second part of my original formula.
(next({table.inmateid})<>{table.inmateid}
// this means count it becasue the pair is not closed and they are still out
or
(next({table.inmateid})={table.inmateid} and
next({Audit_Trail.DateStamp})>{?date param})
)
// this means the next row is for the same inmate which means that logically it is a return row and so the datefield must be > the param in order to count.
 
You should always only see a count on an 'out' row and never on a 'return' row.
Ultimately you do not want to reset your RT at all in order to get a real count.
Does this help with what I was trying to get your set up to do?
