Filtering ON sub query only - sql

Question

I have a query that returns four columns and i want to apply a date range/filter to the two of the columns only , Previously i wrote My query as below.
SELECT TOP (100) PERCENT dbo.Collector.name,
dbo.Debtor.batchno AS batchno,
COUNT(dbo.Debtor.id) AS cases,
SUM(dbo.Debtor.totalDebt) AS amount,
SUM(dbo.Payment.payment) AS collection,
SUM(dbo.Debtor.balance) AS OSBalance,
dbo.debtor.receivedDate
FROM dbo.Payment WITH (NOLOCK)
INNER JOIN dbo.Collector WITH (NOLOCK)
ON dbo.Payment.collectorid = dbo.Collector.id
INNER JOIN dbo.Debtor WITH (NOLOCK)
ON dbo.Payment.debtorid = dbo.Debtor.id
INNER JOIN dbo.Client WITH (NOLOCK)
ON dbo.debtor.clientid = dbo.Client.id
WHERE dbo.Payment.paymentdate BETWEEN ' 2011-02-27 00:00:00.000 '
AND '2014-02-27 23:59:59.000'
AND dbo.Payment.confirmed='Y'
GROUP BY
dbo.Collector.name,
dbo.Debtor.batchno,
dbo.debtor.receivedDate
ORDER BY
dbo.debtor.receivedDate DESC
The above filter all the columns by the paymentdate. However i want the filter by payment date to apply to only two columns namely cases and collecton like below.
SELECT TOP (100) PERCENT dbo.Collector.name,
dbo.Debtor.batchno AS batchno,
(
SELECT COUNT(dbo.Debtor.id)
FROM dbo.Debtor d INNER JOIN dbo.Payment p ON d.id = p.debtorid
WHERE paymentdate BETWEEN ' 2011-02-27 00:00:00.000 '
AND '2014-02-27 23:59:59.000'
AND batchno=dbo.Debtor.batchno
AND dbo.collector.name= dbo.collector.name
) AS cases,
SUM(dbo.Debtor.totalDebt) AS amount,
(
SELECT SUM(dbo.Payment.payment)
FROM dbo.Payment
WHERE paymentdate BETWEEN ' 2011-02-27 00:00:00.000 '
AND '2014-02-27 23:59:59.000'
AND batchno= dbo.Debtor.batchno
AND name= dbo.collector.name
) AS collection,
SUM(dbo.Debtor.balance) AS OSBalance,
dbo.debtor.receivedDate
FROM dbo.Payment WITH (NOLOCK)
INNER JOIN dbo.Collector WITH (NOLOCK)
ON dbo.Payment.collectorid = dbo.Collector.id
INNER JOIN dbo.Debtor WITH (NOLOCK)
ON dbo.Payment.debtorid = dbo.Debtor.id
INNER JOIN dbo.Client WITH (NOLOCK)
ON dbo.debtor.clientid = dbo.Client.id
WHERE dbo.Payment.confirmed='Y'
GROUP BY
dbo.Collector.name,
dbo.Debtor.batchno,
dbo.debtor.receivedDate
ORDER BY
dbo.debtor.receivedDate DESC
The above doesnt work for me. Also i want to group by only batchno and name. Plus the collection and cases columns must filter by payment date . Pls how do i achieve this ? Any help would be appreciated. warmest regard
