Drupal Installation

I’m trying to build a site using Drupal (www.drupal.org) and have managed to install the MYSQL database just fine. However, I can’t seem to connect the drupal software to the database. According to directions, I should set up a variable in the config file like so: mysql://user:password@hostname/database.

However when I then try to connect to my site, I get a “Database problem: DB Error: not found.” Anyone have any advice as to what I might be doing wrong?
