Once a function has returned something, the function stops executing and the script continues from there. Thus, the two returns below the first do nothing as they will never be executed.

Use this:

PHP Code:

$tag_list['option']['count'] = array(  
    'callback' => 'handle_external', 
    'external_callback' => 'handle_bbcode_count_callback',  
    'strip_empty' => true  
);  
   
if(!function_exists('handle_bbcode_count_callback'))  
{  
    function handle_bbcode_count_callback(&$parsed, $value, $option)  
    {  
          $result = 7 + $option;
          return "Hello this is ".$value.",<br /> my number is ".$result;
    }  
}
