error message

I get this message again when I run this script:

BACKUP LOG wslogdb62 WITH TRUNCATE_ONLY
DBCC SHRINKFILE(wslogdb62_log, 1)

This is the error message

Server: Msg 8985, Level 16, State 1, Line 2
Could not locate file 'wslogdb62_log' in sysfiles.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.Ummm ... Cross Post ??
