Help with error install

[coach]

Thought I did everything correct. But got this error below. By looking at other threads I think it is a db connection issue. One said to go to mysql and adjust the connection setting. Not sure how to do it, the only way I am able to do anything to mysql is through phpMyAdmin (I think?). And it doesn't show anything that deals with connections.

[18-Aug-2007 02:00:50 -0400] DB Error: DB Error: connect failed in /home/autoocom/public_html/roundcube/program/include/rcube_db.inc on line 97
[18-Aug-2007 02:00:50] PHP Fatal error: Call to undefined function: query() in /home/autoocom/public_html/roundcube/program/include/rcube_db.inc on line 213

The one thing I was not able to figure out during installation was this:

"For example with mysql enter the following code on the command line:

mysql --user=(your_db_user_name) -p (your_db_name) < mysql.initial.sql"

I'm a newb, so anything will help.
