Problem Connecting to local MAMP Database

I’m trying to set up a connection to a local MAMP Database and keep getting a “Error using this Database Connection! Can not connect to database! Check your network or server address.”

I’ve got my Server Address set to “localhost.” I’ve set my Port to both 8889, 8888 (that’s what I’ve been using on DreamWeaver), and nothing.

My Target is set up with the following info:
Remote Web Server URL: http://localhost/IMEA2
Access Type: Local Folder
Local Folder: file:///Applications/MAMP/htdocs/IMEA2

Any suggestions? I’ve tried various version of the Target info and nothing has worked so far.
