problem with attach database

EXEC sp_attach_single_file_db @.dbname = 'mydatabase',
@.physname = 'c:\Program Files\Microsoft SQL
Server\MSSQL\Data\'mydatabase'.mdf'

Server: Msg 5180, Level 22, State 1, Line 1
Could not open FCB for invalid file ID 0 in database 'mydatabase'.

Connection Broken

What can I do with such error of my database?
Was my database lost?
Any help would be appreciate!
Best regards,
AdamHi

Does the filename really have quotes in it? ( 'mydatabase'.mdf )
