Cannot make connection to local MySQL Server from within Dreamweaver.

I am using OS X and Dreamweaver MX. I am trying to make a connection
to the MySQL Server from within Dreamweaver using the Applications
panel and clicking on the "+". A window opens asking for:
Connection Name: Apress
MySQL Server: localhost
User Name: apress
Password: xxxxxx
Database (Select):
When I click select so the Dreamweaver can browse to the databases in
MySQL the connection is not being made because Dreamweaver cannot find
the MySQL Server. I think that "localhost" is wrong even though I am
using the APRESS book: PHP Dreamweaver MX 2004 and it says to use
localhost. MySQL and PHP are on my local machine. I am NOT using a
remote machine. I used phpMyAdmin to create the databases. Any
suggestions?
