"The > mortgage amount is $mort\n" : " "; Absolute rubbish -- as it says at http://php.net/empty, "empty($var) is the opposite of (boolean)$var, except that no warning is generated when the variable is not set." -- so "protecting" empty() with an isset() is a total waste of time, space and cpu cycles.
