correct mysql errors for cre loaded shop - easy job

Hi all, I had my website files transfered from one server to another, however, it is not loading properly, these are the errors im getting: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'johnlee'@'localhost' (using password: YES) in /home/johnlee/public_html/catalog/includes/functions/[login to view URL] on line 19 Unable to connect to database server! There are other pages not loading which are connected that are getting the same error i.e for Auction Lister Pro but im sure once loaded properly it would all work fine So, basically i need this fixed and tested. Thanks for looking.
