I'm getting an idea of what you're talking about, but the best thing to do would be post the relevant code, esp. your class definition that uses the $vID variable. You're saying that you've set a public $vID var in your class, but where is it set? Is it being set in the 'conf_global.php' script? If so, you need a way to carry that over into the class scope. Using $_SESSION['member_id'] directly inside the class would probably be the best way, as it's a superglobal and has global scope.
