[Zero Tolerance]

The include() function does not return a value, it would be best if you made page.php build up a variable, and then require() the file, after doing that you can then call the variable it has made

Quick Example:
FILE: page.php

PHP Code:

<?php
$myvar = "Hello World!";
?>

FILE index.php

PHP Code:

<?php
require_once("page.php");
echo $myvar;
?>

Hope that helps
