[Plugin: Shortcodes Ultimate] Adding Tab/Tabs Shortcode to Theme

I’m trying to add the tab/tabs shortcodes to my theme, to display a specific type of posts in the tab list.

What’s happening is that my content is displayed successfully, but not inside the tabs. Instead it appears above the tab list. The tabs are created, but are empty.

Below is the code in my template:

<?php $mytabs = '[tabs style="3"]'; ?>
<?php query_posts('post_type=portfolio'); ?>
                            <?php if (have_posts()) : ?><?php while (have_posts()) : the_post(); ?>
                            <?php $title = trim(the_title('<span>', '</span>'));?>
                            <?php $mytabs .= "[tab title=\"".$title."\"]the text[/tab]";?>
                            <?php endwhile; ?>
                            <?php endif; ?>
                            <?php $mytabs .= '[/tabs]'; ?>
                            <?php echo do_shortcode($mytabs);?>
