Have a look here https://www.amibay.com/showthread.php?t=22657 Chinners may be able to help you out.
P.S. The recommended time period for a bump on a thread is three weeks.
Please try to relax and only bump your thread when the three weeks are up or when there is a significant change to the thread, i.e. price drop, item sold, interest expressed, etc.
Thanks, Dave G
