I don't get why I am having issues, I hope I'm just c/p'ing something in wrong and its just a simple fix.

Database is set up on my hosting with a username to access it. All names below are pretend. :)

domain - www.smiley.com

Installed Database - smil_store
DB username - smil_jane

What would go in these spots:

Store Identifier (Table-Prefix)
Database Host
Database Username
Database Name

I currently have, but have tried several ways -

Store Identifier (Table-Prefix) = smil_
Database Host = smileys.com
Database Username = smil_jane
Database Name = store

Using the information above, what all do I put in. Im not sure if I should be putting in full information like "smil_store" or just "store"

I feel like it's an error in what I'm putting in, I appreciate any help. Thanks :)
