SOrry I missed that in your original post.

Firstly I need to suugest that you immediately start ysing mysqli or PDO instead of just mysql as it is now depricated and much less secure than the other two (See Here).
Secondly, you only need to use hostname='', database_name='' etc if using PDO, if just using mysql (or mysqli - just change to mysqli) your database connection should just be:

$marketbase = mysql_connect("hostname","username","password","database") or die("Error " . mysql_error($marketbase));
