no database selected

[Anon]

I get this error time after time when I load news.php (... is left out code, not relevant to the prob)
what's the problem here?

<?php
require("includes/functions.php");
function ShowMain()
{ ... }

in functions.php :

require_once("includes/config.php");
global $dbusername, $dbpass, $dbname, $dbhost, $dblink;

if (eregi("header.php",$PHP_SELF)) {
Header("Location: index.php");
die();}
mysql_connect("$dbhost","$dbusername","$dbpass");
mysql_select_db("$dbname");

function head() { ... }

in config.php the usual vars:

$dbhost = "localhost";
$dbusername = "root";
$dbpass = "";
$dbname = "f1data";

what can be the problem here??
greets,

Try

$conn = mysql_connect("$dbhost","$dbusername","$dbpass");
if (mysql_select_db("$dbname", $conn)) {
print mysql_error();
}
