Hi mwdesign,
To fill out the dbtest.php file you will need to fill in the following information in that file :
$hostname = "YOUR_HOSTNAME";
$username = "YOUR_USERNAME";
$password = "YOUR_PASSWORD";
$db_name = "NAME_OF_YOUR_DATABASE";
Did you create the database on your server or does your host do that? If the latter then you may need to contact them to find out the required information but once you have filled out those pieces of information correctly you should hopefully be able to establish a connection to your database.
The message you are seeing that you showed in your post above will be either because you haven’t filled out that information yet or haven’t filled it in correctly.
If you can find out the correct information and fill that out then let us know what the result is in your browser please.
Thanks.
Mark.
