Authenticate This!

I figured it out. Apparently I had to define my functions outside of the if statement.

Okay... here's the problem.

I have a script that works fine unless I put in some password authentication.  What's happening is that one of my functions is becoming "undefined" once I throw it into an if statement.  In the cut below, you'll see where the authentication ends and the script begins.  I have a feeling it has something to do with globals, but I'm not entirely sure.  Anyone have any ideas?


<?
include("../config.php");
include("../lib/template_class.php");


//Starting the session and using the information.
session_start();
$session=session_id();
$username=$_SESSION['username'];
$password=$_SESSION['password'];



//Calling the database for login/password information.
$result = mysql_query("select * from users where username='$username' AND password='$password' limit 1");
$get_userinfo = @mysql_fetch_array($result);


//Applying DB results to variables.
$username=$get_userinfo[username];
$password=$get_userinfo[password];
$uid = $get_userinfo[id];


//login null checks
if($username=="" AND $password=="" OR $password==""){
	$page = new Page('../template/login.php');
	$page->replace_tags(array(
		'scriptName' => "$scriptName",
		'msg' => "Invalid login or password. Please try again.",
		'footer' => '$footer'));
	$page->output();

	session_destroy();
}else{
