SQL Server 2008 left join where clause based on max date

Got some help the other day on this and now really want to make a change for the better

Here is code

select 
    machines.serialnum, DRPS.assetnumber, DRPS.MOCALCSUM, DRPS.MICALCSUM,
    DRPS.COCALCSUM, DRPS.CICALCSUM, ISSUED.TotalIssued,
    REDEEMED.TotalRedeemed,drps.dropdate1,drps.dropdate2
from
    (select serialnum
     from machineinfo) as machines
LEFT JOIN 
    (select 
        assetnumber, min(dropdate) as [dropdate1], max(dropdate) as [dropdate2], 
        sum(mocalc) AS [MOCALCSUM], sum(micalc) AS [MICALCSUM],
        sum(cocalc) AS [COCALCSUM],sum(cicalc) AS [CICALCSUM]
     from drops
     where dropdate > '09/04/2012' and dropdate < dateadd(hour, -0, getdate())
     GROUP BY assetnumber) AS DRPS on machines.serialnum = drps.assetnumber
LEFT JOIN 
    (select 
        snissued, cast(sum(amount) as money) / 100 AS [TotalIssued] 
     from tickets
     where  dateissued > '09/04/2012' and dateissued < dateadd(hour, 0, getdate())
     group by snissued) AS ISSUED ON machines.serialnum = ISSUED.snissued
LEFT JOIN 
    (select 
         snredeemed, cast(sum(amount) as money) / 100 AS [TotalRedeemed] 
     from tickets
     where  dateredeemed > '09/04/2012' and dateredeemed < dateadd(hour, 0, getdate())
     group by snredeemed) AS REDEEMED ON machines.serialnum = REDEEMED.snredeemed

what I would like to accomplish if possible is for the second and third join is to use the drps.drop1 in the where clause like this

where  dropdate > drps.dropdate1 and dropdate < drps.dropdate2

but it does not work

here is working output

    serialnum   MOCALCSUM   MICALCSUM   COCALCSUM   CICALCSUM   TotalIssued TotalRedeemed   dropdate1   dropdate2
0-2739-41401    5482    5498    132 148 3258.00 3110.00 2012-09-04 13:36:53.450 2012-09-05 13:55:38.750
0-2459-36182    1110    1054    114 58  1895.00 1657.00 2012-09-04 15:01:19.973 2012-09-05 13:55:38.967

end result is I need total issued and total redeemed date range to be between the min and max date per serial number

declare @datebegin datetime
declare @dateend datetime
set @datebegin = '09/04/2012'
set @dateend = '09/08/2012'

select machines.serialnum,     DRPS.MOCALCSUM,DRPS.MICALCSUM,DRPS.COCALCSUM,DRPS.CICALCSUM,ISSUED.TotalIssued,
        REDEEMED.TotalRedeemed,drps.dropdate1,drps.dropdate2

from (select serialnum
    from machineinfo) as machines


LEFT JOIN (select assetnumber,min(dropdate)as [dropdate1], max(dropdate)as [dropdate2], sum(mocalc) AS [MOCALCSUM],sum(micalc) AS [MICALCSUM],
    sum(cocalc) AS [COCALCSUM],sum(cicalc) AS [CICALCSUM]
    from drops
    where  dropdate > @datebegin and dropdate < @dateend AND  (ignore is null)
            group by assetnumber) AS DRPS
    on machines.serialnum = drps.assetnumber
LEFT JOIN (select snissued,cast(sum(amount)as money)/100 AS [TotalIssued] from tickets
where  (dateissued > (select min(dropdate)
                        from drops 
                        where dropdate > @datebegin AND  (ignore is null) and snissued = assetnumber ))
                        and
       (dateissued < (select max(dropdate)
                        from drops 
                        where dropdate < @dateend AND  (ignore is null) and snissued = assetnumber))
group by snissued) AS ISSUED
ON machines.serialnum=ISSUED.snissued
LEFT JOIN (select snredeemed,cast(sum(amount)as money)/100 AS [TotalRedeemed]

from tickets
where  (dateredeemed > (select min(dropdate)
                        from drops 
                        where dropdate > @datebegin AND  (ignore is null)and snissued = assetnumber))
                        and
       (dateredeemed < (select max(dropdate)
                        from drops 
                        where dropdate < @dateend AND  (ignore is null)and snissued = assetnumber ))

group by snredeemed) AS REDEEMED
ON machines.serialnum=REDEEMED.snredeemed
order by REDEEMED.TotalRedeemed desc

based on the suggestion from comments i added the subquery into the selects and i am getting expected results now
