Help! Can't find the database name?

[kjgo]

I'm trying to install Wordpress, but I keep receiving this error:
Can’t select database
We were able to connect to the database server (which means your username and password is okay) but not able to select the ######## database.

Are you sure it exists?
On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?
If you don't know how to setup a database you should contact your host. If all else fails you may find help at the WordPress Support Forums.

(I put #### in place of the database name, in case it isn't supposed to be public knowledge). What am I doing wrong?

You can log into OPS, then click MySQL, then look at the database server name and the database name. Your database server name is username.powwebmysql.com where username is your username for OPS. Your database name should be visible there. PowWeb doesn't put a prefix with your username in the name of your database.
