	<? include('head.inc.php'); ?>
		<? include('menu.php'); ?>

		<table class='normal_table width_1000' cellspacing="1">

				$query = "SELECT * FROM `trunk_groups` WHERE 1=1";
				$result = mysql_query($query) ;//or die   ("Query failed with error: ".mysql_error());
				while ($tmp = mysql_fetch_array($result)){
					$id 			= $tmp['trunk_group_id'];
					$name 			= $tmp['name'];
					$auto_refill		= $tmp['auto_refill'];
					$min_seconds		= $tmp['min_seconds'];
					$refill_threshold 	= $tmp['refill_threshold'];

					echo "</tr>";

and bd.inc.php

	$db_host = "localhost";
	$db_user = "asterisk";
	$db_password = "joco15";
	$db_name = "asterisk";
	$mysql_link = mysql_connect($db_host,$db_user,$db_password) or die (mysql_error());


thx a lot inadvance.

Wrong user/password when trying to connect. The other two are follow-up errors.

use this to connect to a database


$con=mysql_connect("localhost", $user, $pass)
or die ('Couldnt connect to server');
or die('could not connect to db');

yeah this worked for me
thx guys a lot
