mySQL host

I shall install a script, and I run install.php on the script and I have to type in the database host, name, username and password.....

But this comes up when I click OK:

Error:
Host 'ritsuko.ezzi.ne' is not allowed to connect to this MySQL server

I don't have "localhost" as my mysql host here.... because I shall only run the script on this mySQL database... not the site... the site I run from another web server....

Standard database users have permissions ONLY from localhost when created in DA.

To fix this or change it go to phpmyadmin:

http://[domain]/phpmyadmin/

In the permissions/rights section you add an other user wich can access the table/database from a specific location. Or just change the current user

Ok...

I have never been in phpmyadmin before...
Can u help me tell me were on phpmyadmin I can change the permissions/users?

I run phpMyAdmin 2.6.0-pl1........
