I think you need to change the syntax of the raiserror line.

Here it is from BOL:

RAISERROR ( { msg_id | msg_str | @local_variable }

{ ,severity ,state }

[ ,argument [ ,...n ] ] )

[ WITH option [ ,...n ] ]

--EXAMPLE

RAISERROR (N'This is message %s %d.', -- Message text.

10, -- Severity,

1, -- State,

N'number', -- First argument.

5); -- Second argument.

-- The message text returned is: This is message number 5.

GO

There's no such thing as an 'updated' table. The two pseudo-tables visible in triggers are inserted and deleted.

Inserted contains new rows, when the operation is an insert, and the new values, when the operation is an update. Deleted contains the old values, when the operation is an update, and the rows to be deleted when the operation is a delete.

Also to note is that a trigger fires once per statement and the inserted and deleted tables contain all rows affected. The way your trigger is written it'll throw the error any time more than 2 rows are inserted, updated or deleted in the Participants table, regardless of the value of the columns.
