message.php - problems

[kp380lv]

When i send message on my profile then shows this error




and then refresh to my inbox!



Which file is guilty?
I think its message.php

header ("Refresh: 2; url=message.php");
stdsuccsess($tracker_lang['success'] , $message_lang['sendsucessfull']);
}

Fatal error: Call to undefined function stdsuccsess() in C:\Program Files\xampp\htdocs\message.php on line 420
