Hi again everyone, I just need some quick help with connecting to a mysql database in dreamweaver.
I'm using a freebie account on ulmb.com, and I've got a database set up with tables ready to go. However, when I enter my details, I get a 404 error.
Here's a link to the picture of what I enter:

Database Server Name: mysql
Database: 15909_rsxpress
Username: 15909_rsxpress
Table Names:

user_password
Thanks in advance!
