PHP error on uploaded page

Hi,

I am new in PHP and MySQL so apologize for stupid question.

Still trying trialout version of PHPrunner on WinXP Pro SP3, IIS5, PHP 5.2.6, MySQL5.

I generated testing site with PHPrunner into C:\Inetpub\wwwroot\output. It works fine on my localhost server.

http://localhost/output/

When I upload all files from "output" folder to "jirka" folder with demo account on asprunner server its working fine too.
see it here
When I upload all files from "output" folder to "jirka" folder on my own hosting server at hostmonster.com its show error.
PHP error happened

Technical information

Error type 2

Error description mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES)

URL petrspage.com/jirka/cars_list.php?

Error file /home/miroscre/public_html/petrspage/jirka/include/dbconnection.php

Error line 9

SQL query
see it here
I think it is something about communicating with database.

Connection was created on localhost server and it does not work o remote server.

Maybe I am wrong. Any ideas how to make it work?

Thanks Petr
