Installing the Calendar. newbee

I have never done this before. Where the script calls for database name I entered "antiques" . For a db host I entered mysql.wtiwebhosting.com...I am getting this error msg: Seems there was a problem selecting the database you specified. Please check the ltw_config.php file to make sure the proper values are entered there.
The error (if any) returned from the database was:
Access denied for user: 'jackknyc@64.49.223.222' to database 'antiques' . I did nothin else.What do I do next? Thanks in advance.

Sounds like you may have entered a wrong user name or password for your database. Check those values and be sure they are correct...

So far this is all I have done. I did not create the database anywhere and I got the db host info from my PHPBB config file.
I made these changes and tried to run the itw_install script when I got the error

Thanks for your help,
Jack

this is the part I changed;

//the following variables are for your database connection.
//Currently only db_type of 1 is supported. 1 = MySQL
$ltw_config['db_type'] = 1;
$ltw_config['db_server'] = 'mysql.wtiwebhosting.com';
$ltw_config['db_name'] = 'antiques';
$ltw_config['db_user'] = 'myname';
$ltw_config['db_pass'] = 'mypass';
$ltw_config['db_persistent'] = false;
