Custom section in course sidebar

HI, is it possible to add an editable region that will display in the sidebar above the add to cart  button? Specifically I would like to display course title, date, location and price in a list. I have tried adding the following code so tjhey can be added but nothing has changed in course settings. Thanks!   ' add_filter('wplms_course_metabox','wplms_custom_course_details_repeatable'); function wplms_custom_course_details_repeatable($metabox){ $metabox['vibe_course_details'] = array( 'label' => __('Custom Course details','vibe-customtypes'), // <label> 'desc'  => __('custom course details.','vibe-customtypes'), // description 'id'    => 'vibe_course_details', // field id and name 'type'  => 'repeatable', // type of field 'std'   => '' ); return $metabox; }   add_filter('wplms_course_details_widget','wplms_custom_course_details_information'); function wplms_custom_course_details_information($details){ $custom_info = vibe_sanitize(get_post_meta(get_the_ID(),'vibe_course_details',false)); if(isset($custom_info) && is_array($custom_info)){ foreach($custom_info as $k=>$val){ $details[]='

• '.htmlspecialchars_decode($val).'

'; } } return $details; }'
