Bug in Responsive WordPress Themes: Single Post (single.php)

In the code you have:

/* =============================================================================
LOAD PAGE TEMPLATE
========================================================================== */

$GLOBALS[‘flag-single’] = 1;

// ADD-ON PLAYER FILES ENCASE WE HAVE VIDEO
wp_enqueue_script(‘video’, get_template_directory_uri().’/framework/player/mediaelement-and-player.min.js’);
wp_enqueue_script(‘video’);

wp_enqueue_style(‘video’, get_template_directory_uri().’/framework/player/mediaelementplayer.min.css’);
wp_enqueue_style(‘video’);

// ADD-ON SLIDER STYLES
wp_enqueue_script(‘slider’, get_template_directory_uri().’/framework/slider/jquery.flexslider-min.js’);
wp_enqueue_script(‘slider’);

wp_enqueue_script(‘prettyphoto’, get_template_directory_uri().’/framework/slider/jquery.prettyPhoto.js’);
wp_enqueue_script(‘prettyphoto’);

wp_enqueue_style(‘slider’, get_template_directory_uri().’/framework/slider/flexslider.css’);
wp_enqueue_style(‘slider’);

wp_enqueue_style(‘prettyphoto’, get_template_directory_uri().’/framework/slider/prettyPhoto.css’);
wp_enqueue_style(‘prettyphoto’);

// UPDATE VIEW COUNTER
$CORE->HITCOUNTER($post->ID);

// ADD IN TOOLBOX FOR AUTHOR DATA
add_action(‘hook_single_after’,array($CORE, ‘AUTHOR_TOOLBOX’) );

which says if ‘x’ example wp_enqueue_script(‘slider’, get_template_directory_uri().’/framework/slider/jquery.flexslider-min.js’);
wp_enqueue_script(‘slider’);

then print in header the css and js for flexslider, but I have found that this is not working as intended, if there is no flex slider or outhes ie pretty phot the code is still printed in the header.
