Not Much Success With MULTI DELETE

Trying to delete records associated with the same contact id from all the tables used for that contact. But I'm getting an error. Strange error because the table does exist and I've been able to do single deletes from that table. So, something tells me I'm not getting something right in my SQL statement. How do I delete records from all 3 tables using the same id (as opposed to doing 3 different SQL calls, one for each)?

-----------------
DELETE names, addresses, phones
FROM names AS n, addresses AS a, phones AS p
WHERE n.id = '12' AND a.id = '12' AND p.id = '12'

Error: Unknown table 'names' in MULTI DELETE
-----------------

(BTW, how do tag my code so it shows up in a code div?)
