php public function, include problem

[B]Hej allesammen.[/B]
når jeg prøver at lave en include i min functions.php virker det, men kun over class Wall_Updates {, der kan jeg finde alle mine varialbes fra min include, men når jeg går under class Wall_Updates { så kan den ikke finde dem, hvorfor? og hvordan kan jeg så gøre?






<?php
include("../include/session.php");

class Wall_Updates {
