Drupal Installation: 'unable to select database'

I’m trying to get Drupal set up for one of my domains.

I’ve uploaded the files, created the mySQL, and modified
the ‘setttings.php’ file with the correct info.

But when I go to view the website, i get the following:

‘unable to select database’

what does that mean? is that a priviledges problem?
I went to the database using phpMyAdmin - and
I don’t see anything obviously wrong with the database -
it does say “No Privileges” in red letters, right underneath “create new database header”

If it is a priviledges problem, how to a modify them for my database? I’ve been looking through phpMyAdmin and I don’t see how.
