question

I am trying to run this stored procedure to kick off an SSIS Package

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER procedure [dbo].[RunSSISRemitCreate]

@BatchNumber1 as VARCHAR(8),
@BatchNumber2 as VARCHAR(8),
@BatchNumber3 as VARCHAR(8),
@BatchNumber4 as VARCHAR(8),
@BatchNumber5 as VARCHAR(8),
@BatchNumber6 as VARCHAR(8),
@BatchNumber7 as VARCHAR(8),

@result as int output

as

Declare @cmd varchar(1000)  
declare @FilePath varchar (50)
set @FilePath = 'E:\SSIS Packages\HSIS'
declare @Filename  varchar (30)
set @Filename = '\SSISRemit.dtsx'

--select @cmd =  'dtexec /REP N /F "' + 'E:\SSIS Packages\HSIS\SSISRemit.dtsx '+ '"' + ' /De test' 
select @cmd =  'dtexec /REP N /F "' +  @FilePath + @Filename + '"' + ' /De test' 
                                    + ' /Set \package.variables[BatchNumber1].Value;' + @BatchNumber1
                                    + ' /Set \package.variables[BatchNumber2].Value;' + @BatchNumber2
                                    + ' /Set \package.variables[BatchNumber3].Value;' + @BatchNumber3
                                    + ' /Set \package.variables[BatchNumber4].Value;' + @BatchNumber4 
                                    + ' /Set \package.variables[BatchNumber5].Value;' + @BatchNumber5
                                    + ' /Set \package.variables[BatchNumber6].Value;' + @BatchNumber6
                                    + ' /Set \package.variables[BatchNumber7].Value;' + @BatchNumber7


exec @result = master..xp_cmdshell @cmd
RETURN @result


--[dbo].[RunSSISRemitCreate] '116965002','116965004','116965008','116965012','117022189','0','0',0

I get this error ....
