Subquery Error

Dear Friends,

Could you tell me where is the problem?

ALTER PROCEDURE [dbo].[GD_SP_FACTURA_SOFTWARE_GERAL2]
@Direccao nvarchar(10)
AS
DECLARE @NrLinha int
BEGIN

SET @NrLinha = SELECT COUNT(*)
FROM
(SELECT dbo.Aplicacao.Aplicacao, COUNT(dbo.ADCN_AplicID.CN) AS QtAplic
FROM dbo.ADCN_AplicID INNER JOIN
dbo.Aplicacao ON dbo.ADCN_AplicID.AplicID = dbo.Aplicacao.AplicID INNER JOIN
dbo.SERVICO ON dbo.ADCN_AplicID.Servico = dbo.SERVICO.S_GrupoServico INNER JOIN
dbo.HARDWARE ON dbo.ADCN_AplicID.CN = dbo.HARDWARE.New_Computername
WHERE (dbo.SERVICO.S_NomeDir = @Direccao)
GROUP BY dbo.Aplicacao.Aplicacao, dbo.Aplicacao.Custo
)

END
