can this be done, but I keep getting syntax errors.

I need to count the # of rows returned from this:
SELECT DISTINCT Customer
FROM dbo.TestBlockStatus
WHERE (ModelEnum = 0) AND (SystemName = '2731')

But this does not work, why ?? & how to fix it ( Thanks ! )

SELECT COUNT(*) AS inTotal
FROM dbo.TestBlockStatus
(WHERE SELECT DISTINCT Customer
FROM dbo.TestBlockStatus
WHERE (ModelEnum = 0) AND (SystemName = '2731')) as A

[code]
SELECT count(DISTINCT Customer) as inTotal
FROM dbo.TestBlockStatus
WHERE (ModelEnum = 0) AND (SystemName = '2731')
[/code]
