Trouble with fresh install

I did CMOD on the necessary files and ran install.php. I filled in the blanks and got this message:
Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'nimandir_amarth'@'localhost' (using password: YES) in /home/nimandir/public_html/forum/db/mysql4.php on line 54
