Multiple Loop?

I have litle question.

I was mad more than Loop on my WP. First loop will show the post from categories 18 and other loop will loop post from categories 34.

And I was add my first loop on index.php and other loop in sidebar.php with this code

on index.php

<?php include (TEMPLATEPATH . '/cat18.php'); ?>


on sidebar.php

<?php include (TEMPLATEPATH . '/cat34.php'); ?>


My problem is, when I test in my browser. The loop not show all. My WP just show from cat18.php and the cat34 disappear.

What wrong?

This my cat18.php loop

<?php query_posts('category_name=News&showposts=4'); ?>


and on cat34.php loop

<?php query_posts('category_name=Promo&showposts=4'); ?>


*note News is my categories 18 and Promo is my categories 34.
