Restoring Log Backups

I´m having a problem when trying to restore log backups.
After i had restored my Data backup leaving it able to restore aditional tra
nsaction logs, i start the commands to restore my log backups:
RESTORE LOG [ACS] 
FROM  DISK =  N'D:\BACKUPTRABALHO\
acs\BKP_ACS_LOG' 
WITH  FILE = 24,  NOUNLOAD ,  STATS = 10,  STANDBY =  N'D:\BACKUPTRABALHO\
ACS
\UNDO_ACS.DAT'

The files are between 24 and 32, but the file 32 I want to restore until a s
pecifc point in time. I´m utilizing the following statment to restore the fi
le 32:
DECLARE @DATA DATETIME
SET @DATA = '2006-03-22 00:00:00'

RESTORE LOG [DB_ACS] 
FROM  DISK =  N'D:\BACKUPTRABALHO\
ACS\BKP_ACS_LOG' 
WITH  FILE = 32,  NOUNLOAD, STATS = 10,  RECOVERY,
STOPAT = @DATA -- '2006-03-22 00:00:00'

The result of the execution of the statemment above is:

Deleting database file  'D:\BACKUPTRABALHO\A
CS\UNDO_DB_ACS.DAT'.

?
