Cannot run the script provided by config tool

Hello!

I'm new to both multisite and multi-db.

I tried to run this on SQL tab in PHPMY Admin:

CREATE DATABASE aw1ms2_global DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

but I got this error:

#1044 - Access denied for user 'misiedum'@'localhost' to database 'aw1ms2_global'

What's wrong?
