Getting Rowcount From Subquery In Stored Procedure

I'm trying to get the Rowcount from an inner select statement into an output parameter of a stored procedure. The following code returns the count from the outer select statement but when I try moving the 'SET @RecordCount = @@RowCount' line into the inner select statement I get errors. I've spent hours trying to get this to work but so far have not been able to do so.


ALTER PROCEDURE [dbo].[spProductSelectionAsp-test]

-- Add the parameters for the stored procedure here

@Product char(20) = null,

@PageSize int = 20,

@Page int = 1,

@RecordCount int = null OUTPUT

AS

BEGIN

SET NOCOUNT ON;

-- Insert statements for procedure here

SELECT TOP(@PageSize) * FROM

(

SELECT row_number() OVER (ORDER BY SKU.SIZE, SKU.COLOR) AS RowNumber,

SKUWH.RECNUM, SKUWH.AVAILABLE, SKU.STATUS, SKU.P1

FROM SKU INNER JOIN

SKUWH ON SKU.MASTER_NO = SKUWH.MASTER_NO INNER JOIN

SKUMKTG ON SKU.SKUMKTG_UID = SKUMKTG.UNIQUE_ID

WHERE (SKUMKTG.PRODUCT_# = @Product)

)

as _myResults

WHERE RowNumber > (@PageSize * (@Page - 1))

SET @RecordCount = @@RowCount

END

Any suggestions would be greatly appreciated.
Thanks,
Chris
