Er........ coma king.... could you please look towards the bottom of the post list and find the 2 buttons - one marked "NEW Thread", the other, "Post Reply"????
Guess what each does... if you hit New Thread... it starts a new topic of discussion. If you hit Post Reply, it adds you answer to the thread you are currently responding to....
You're hitting "New Thread" each time you answer someone's post, creating a series of disjointed threads all over the place...........
Thanks,
Bruce
