I think I'm being incredibly dense here
It doesn't seem to want to work.
I've substituted localhost, my user name, and my password and I still get a blank page.
I've uploaded the code as I have it at the moment (including username and password. If you try to load the link above now you should just see the blank page (but you'll be able to see the source as well).
Maybe someone can spot what I'm doing wrong?
