mysql error message

Ok here's the following script:

<?

$connection = @mysql_connect($db_server,$db_user,$db_password)
or die ("Can't connect to Database");

@mysql_select_db($db_database,$connection)
or die ("Can't connect to Database");

$alias="dega";
$result = mysql_query("select * from emulator_data where emulator_alias='$alias'");

while ($row = mysql_fetch_array($result)) {

$id = $row["id"];
$emulator_name = $row["emulator_name"];
$emulator_alias = $row["emulator_alias"];
$os_platform = $row["os_platform"];
$version = $row["version"];
$release_date = $row["release_date"];
$size = $row["size"];
$whatsnew = $row["whatsnew"];
$download_link = $row["download_link"];
$download_times = $row["download_times"];
$homepage = $row["homepage"];

$bordercolor = "#000000";
$headercolor = "#A1CDDF";
$bgcolor = "#FFFFFF";
$font = "Verdana, Arial";

echo "some crap";

}

mysql_close($connection);

?>

All's wel but mysql_close doesn't recognize $connection as an previous made connection.
Whats up with that?

Try to call mysql_query with $connection as argument....
(why you need $connection, if you don't use it )
