re-order tabs

Hi all,

wonder if anyone can help…
What am I doing wrong?!

Set up custom tab, want it to appear after images, but won’t!
Any advice appreciated. Thank you.

// this is the snippet that adds the filter, calling the function below. 
add_filter('geodir_detail_page_tab_list_extend', 'geodir_detail_page_tab_list_extend') ;
 
// this is the function that does the re-ordering that we call with the add filter snippet above.
function geodir_detail_page_tab_list_extend($tab_array)
{
 
 // here you can modify the array and re-arrange tabs as you wish, you can create a completely new array too.
 

    // this is the images tab
    if(isset($tab_array['post_images'])){
         $new_tab_array['post_images'] = $tab_array['post_images'];// set in new array
         unset($tab_array['post_images']);//unset in old one

    }
    // 
    if(isset($tab_array['post_special_offers2'])){
         $new_tab_array['post_special_offers2'] = $tab_array['post_special_offers2'];// set in new array
         $new_tab_array['post_special_offers2']['is_active_tab']='1';
         unset($tab_array['post_special_offers2']);//unset in old one
     }

    // this is the special offer tab
    if(isset($tab_array['special_offers'])){
         $new_tab_array['special_offers'] = $tab_array['special_offers'];// set in new array
         $new_tab_array['special_offers']['is_active_tab']='5';
         unset($tab_array['special_offers2']);//unset in old one
     }

    // this is the post info tab (optional for custom fields)
    if(isset($tab_array['post_info'])){
         $new_tab_array['post_info'] = $tab_array['post_info'];// set in new array
         $new_tab_array['post_info']['is_active_tab']='4';
         unset($tab_array['post_info']);//unset in old one
     }

    // now we set any remaining tabs that have not been assigned an order
    foreach($tab_array as $key=>$tab){
    $new_tab_array[$key]=$tab;
    }
 
    return $new_tab_array ;
}

    // this is the post profile tab
    if(isset($tab_array['post_profile'])){
         $new_tab_array['post_profile'] = $tab_array['post_profile']; // set in new array
         // IMPORTANT the following code tells GeoDirectory that this is no longer the default active tab 
         $new_tab_array['post_profile']['is_active_tab']='98';
         unset($tab_array['post_profile']);//unset in old one
     }
 

    // this is the map tab
    if(isset($tab_array['post_map'])){
         $new_tab_array['post_map'] = $tab_array['post_map'];// set in new array
         $new_tab_array['post_map']['is_active_tab']='99';
         unset($tab_array['post_map']);//unset in old one
     }
 
    // this is the related listing tab
    if(isset($tab_array['related_listing'])){
        $new_tab_array['related_listing'] = $tab_array['related_listing'];// set in new array
         $new_tab_array['related_listing']['is_active_tab']='100';
        unset($tab_array['related_listing']);//unset in old one
    }
