it looks like you are using the delivery_fee of the location table:
$colname_rsDeliveryFee = "-1";
if (isset($_POST['DeliveryCity'])) {
$colname_rsDeliveryFee = (get_magic_quotes_gpc()) ? $_POST['DeliveryCity'] : addslashes($_POST['DeliveryCity']);
}
mysql_select_db($database_cupcakes, $cupcakes);
$query_rsDeliveryFee = sprintf("SELECT * FROM delivery_fee WHERE location = %s", GetSQLValueString($colname_rsDeliveryFee, "text"));
$rsDeliveryFee = mysql_query($query_rsDeliveryFee, $cupcakes) or die(mysql_error());
$row_rsDeliveryFee = mysql_fetch_assoc($rsDeliveryFee);
$totalRows_rsDeliveryFee = mysql_num_rows($rsDeliveryFee);
