Select multiple categories with checkboxes

Hi, it’s me again … 😉 Didn’t get no reply before, so…
Here’s the situation:
I have, let’s say, 5 categories:“Stores”, “Museums”, “Garages”, “Sports”, “Towns”, and the last one – “Towns” is hidden (excluded) from cateogries menus.
I would like to, when I click on “Stores”, and I get archive page with posts in that category, on the top of that page is form with checkboxes to select child categories of “Towns”.
So, I would like that I, while on “Stores” archive page,can check one or few boxes with towns, and when clicks “Submit” to display posts that are in – “Stores” AND “New York” AND “Washington” (in other words – stores located in N.Y and Washington).
Here my code, so far (which doesn’t work, off course):
```
<?php $cat_ID = $cat; ?>
<form action="<?php query_posts(array('category__and' => array($cat_ID,array($categories->term_id)))); ?>">
<?php $categories=get_categories('child_of=5&hide_empty=0');
	foreach($categories as $category) {
		echo "<input type='checkbox' name='mychecky' value='$category->term_id' />";
		echo $category->cat_name;
		echo '<br />';    }
	?>
	<INPUT TYPE=SUBMIT VALUE="submit">
</form>

<?php while (have_posts()) : the_post(); ?> ... etc (the loop here ..)
```
Any help is really much appretiated …

Ok, I have update, so ignore upper code. Just read the “story” 😉
This code bellow is, I believe on the right track, it just has one flaw – it doesn’t work :D.
Something is wrong with the category__and part, because when my if loop runs query_posts without category__and it’s ok. When I select checkbox option, the page goes completely blank … 🙁 (?)
Here’s code:

<?php $current_cat_ID = $cat; ?>

<form method="post" action="" id="mjesta">

	<?php
	$categories=get_categories('child_of=104&hide_empty=0');
	foreach($categories as $category) {
		echo '<div class="mjesto">';
		echo "<input type='checkbox' name='place_id[]' value='$category->term_id' />";
		echo '<span>'.$category->cat_name.'</span>';
		echo '</div>';
	}//end foreach

	$place_id=$_POST['place_id'];
	while (list ($key,$val) = @each ($place_id)) {
		$v = "$val,";
		echo $v;
	}//end while
	?>
	<br />
	<input type="submit" value="<?php echo(__('show','rab')); ?>" id="botun">
</form>

</div>

<?php
if(empty($v)) {
	query_posts('cat='.$current_cat_ID.'&showposts=5&orderby=title&order=ASC');
}else{
	query_posts(array('category__and'=>array($current_cat_ID,$v),'posts_per_page'=>2,'orderby'=>title,'order'=>DESC));
}//end if
 ?>

<?php while (have_posts()) : the_post(); ?> ... and so on ...

Pleeeease, help !
