Problem with pagination (v1.5.3)

Hi!  I have two includes on the same page. When I click on the pagination of one them, applies to both includes.

<div>
<?php
$static=TRUE;
$number="16";
$category="1";
include("/my_site/cutenews/show_news.php");
?>
</div>

<div>
<?php
$static=TRUE;
$number="16";
$category="2";
include("/my_site/cutenews/show_news.php");
?>
</div>

When I click on the next button of the include with category 2, change the pagination of category 1. Need to be independent.
In the browser bar shows :http://my_site/index.php?start_from=16&ucat=2  ---->but change the category 1.

Please helpme, I've tried everything I know.
