get_category_tags function clean up

Hello Guys, I hope its OK that I post my question here. I am trying to modify this script to show taxonomys inside another taxonomy.

This is what I got, any help would be great:

function get_tax_tags($args) {
	global $wpdb;
        $tp = $wpdb->prefix;
	$tags = $wpdb->get_results
	("
		SELECT DISTINCT terms2.term_id as tag_id, terms2.name as tag_name, null as tag_link
		FROM
			wp_posts as p1
			LEFT JOIN wp_term_relationships as r1 ON p1.ID = r1.object_ID
			LEFT JOIN wp_term_taxonomy as t1 ON r1.term_taxonomy_id = t1.term_taxonomy_id
			LEFT JOIN wp_terms as terms1 ON t1.term_id = terms1.term_id,

			wp_posts as p2
			LEFT JOIN wp_term_relationships as r2 ON p2.ID = r2.object_ID
			LEFT JOIN wp_term_taxonomy as t2 ON r2.term_taxonomy_id = t2.term_taxonomy_id
			LEFT JOIN wp_terms as terms2 ON t2.term_id = terms2.term_id
		WHERE
			t1.taxonomy = 'rea' AND p1.post_status = 'publish' AND terms1.term_id IN (".$args['categories'].") AND
			t2.taxonomy = 'outlet' AND p2.post_status = 'publish'
			AND p1.ID = p2.ID
		ORDER by tag_name

	");
	$count = 0;
	foreach ($tags as $tag) {
		$tags[$count]->tag_link = get_tag_link($tag->tag_id);
		$count++;
	}
	return $tags;
}

And my “show” function:

function yrken15() {

if ( is_tax( 'rea' )) {
global $wp_query;
$tax = $wp_query->queried_object;

	print "\n" . '<ul class="featured-brands25" style="list-style: none;">';
echo '<h3>Du kan handla ' . strtolower(single_cat_title( '', false )) . ' från följande varumärken</h3>'; 

$the_id = $tax->term_id;

echo $the_id;
$tags = get_tax_tags($the_id);

sort($tags);

foreach ($tags as $tag) {

print "\n" . '<li>';
			print "\n\t" . '<p style="text-align: center;"><a class="classname2" href="' . get_home_url() . '/outlet/' . strtolower(str_replace(' ', '-', $tag->tag_name)) . '/">' . strtolower($tag->tag_name) . '</a></p>';
			print "\n" . '</li>';

}
	print "\n" . '</ul>';

}

else if ( is_tax( 'outlet' )) { 

}

else { 

}
}

Getting the tax->term_id works fine (as the echoing line will tell) but no results shows up, any idea why? Also I found that when I am using the original setting with category and tags, the function works on some of my webhosts but not on other, why would that be?

Thank you guys in advance!
