installation error message - HELP!

[gepimoney]

This error message keeps appearing whenever I try to install Coppermine:

mySQL Error: Access denied for user 'gepimoney'@'localhost' to database 'mysql' on query ' CREATE TABLE IF NOT EXISTS sessions ( session_id varchar(40) NOT NULL default '', user_id int(11) default '0', time int(11) default NULL, remember int(1) default '0', PRIMARY KEY (session_id) ) TYPE=MyISAM COMMENT='Used to store sessions''

I don't know what it means.
I have Yahoo! Small Business and have done everything in this thread >> http://coppermine-gallery.net/forum/index.php?topic=18943.0

I don't think you did. The post you link to says: Instead of "localhost" for the mysql server, use "mysql".

The error message you posted says you used localhost for the server name and mysql for the database name, which is almost certainly wrong. This is not something w can help you with - you need to obtain the correct details from your webhost.
