Problem creating table

[Perfidus]

Hi there; I'm using phpmyadmin to create a table in a database that I havent create myself, it looks like I'm missing some permissions or something is wrong because it doesn't allw me to write:
THE QUERY

CREATE TABLE `commonusers` (

`id` SMALLINT( 6 ) NOT NULL AUTO_INCREMENT ,
`user` VARCHAR( 20 ) NOT NULL ,
`pass` VARCHAR( 20 ) NOT NULL ,
`dep` VARCHAR( 100 ) NOT NULL ,
`priv` VARCHAR( 100 ) NOT NULL ,
PRIMARY KEY ( `id` )
)


THE ERROR MESSAGE:
#1 - Can't create/write to file './thedatabase/usuarios.frm' (Errcode: 13)

Does anybody have a hint for me about what can be going on?
The mysql manual is really poor about this issue.

it's exactly what you just said. the user that the web server is running under doesn't have access to the directories the DB is in.

Yeah, is exactly this, the access was only granted under plesk...
Thank's for your tip.
