Where clause in EXEC master..xp_cmdshell 'bpc"

Hello Experts,

I have created the following BCP script below, but keep receiving the error that follows when I execute it.  I can run it without the where clause just fine.

declare @move_dt                                    datetime
            , @move_yyyymmdd                              varchar(8)
            , @move_letter_file_location            varchar(2000)
            , @bcp_move_cmd                                    varchar(2000)



set @move_dt = convert(datetime,'7/1/2008',101)
set @move_yyyymmdd = right(replicate('0',4) + cast(datepart(yyyy, @move_dt) as varchar(4)),4) + right(replicate('0',2) + cast(datepart(mm, @move_dt) as varchar(2)),2) + right(replicate('0',2) + cast(datepart(dd, @move_dt) as varchar(2)),2)


set @move_letter_file_location = '\\server\move_' + @move_yyyymmdd + '.txt'

set @bcp_move_cmd = 'bcp "select * from database..address_view where (right(replicate("0",4) + cast(move_yyyy as varchar(4)),4)) + (right(replicate(0,2) + cast(move_mm as varchar(2)),2)) + (right(replicate(0,2) + cast(move_dd as varchar(2)),2)) =  @move_yyyymmdd order by 3" queryout "'
set @bcp_move_cmd = @bcp_move_cmd + @move_letter_file_location + '" -t -c -SDEV_SQL -T'


EXEC master..xp_cmdshell @bcp_move_cmd


Error i am receiving:
