multiple primary key exception

[niya nair]

hai all
i am getting an exception like
MySQLSyntaxErrorException multiple primary key defined.
my query is

CREATE TABLE `first_item` (
`itemid` int(5) unsigned NOT NULL default '0',
`subitemid` int(5) unsigned NOT NULL default '0',
PRIMARY KEY (`itemid`,`subitemid`)
)
i am using innodb as the database engine.
can someone give me any suggestion please.

thanks

Your CREATE TABLE statement does execute in MySQL, and it creates a table.
