slider.php file not working

My homepage slider on my site http://www.brewrecords.net should slide to the next featured image but it doesn’t, also the little arrows at either side of the image attempt to direct you to http://www.brewrecords.net/#blank , maybe this is part of the problem?

everything appears to be normal in the settings…5 second intervals but the image does not move at all.

My slider.php code is below, can anyone advise?

<div class="jFlow"> 

            <div id="prev_btn">
                <a href="#blank"><img src="<?php bloginfo('template_url'); ?>/images/blank_btn.gif" alt="Previous Tab" class="jFlowPrev" /></a>
            </div>
            <div id="next_btn">
                <a href="#blank"><img src="<?php bloginfo('template_url'); ?>/images/blank_btn.gif" alt="Next Tab" class="jFlowNext" /></a>
            </div>

            <div id="slides">
                <?php $recent = new WP_Query("cat=" .ot_option('slider_cat'). "&showposts=" .ot_option('slider_num') ); while($recent->have_posts()) : $recent->the_post();?>
                <div>
                    <span class="jFlowControl"></span>
                    <a href="<?php the_permalink() ?>" rel="bookmark"><?php the_post_thumbnail( 'home-feature' ); ?></a>
                    <h4><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h4>
                    <?php the_excerpt(); ?>
                </div>
                <?php endwhile; ?>
            </div>

        </div>
