Session variables problem in functions

I am having problems with initializing session variables inside functions
While writing PHP scripts I need to set some session variables inside some functions
Example:
             function some_function()
             {
                    ...........
                    session_register("message");
                    $message="You are NOT authorized to view this page";
                   ........
             }

The same code for setting session variables in working fine when I use in the main part of the PHP i.e. not inside any function.

Can anyone figure out my mistake in setting session variables??

Suggestions and solutions are welcome

Use the super global variable $_SESSION["message"] instead

$message =& $_SESSION['message'];

$message = $_SESSION['message'];

No Shivsa, put the & back in.

Otherwise the value will be lost, after he exits the function.
Alternatively

$message = &$_SESSION['message'];

could be used, the difference is that with my first one, you are using the copy by reference operator, where as in my second example you are copying a reference.
