I've merged the two threads. Sorry I misunderstood your first post. When I saw "thank you" I had the mistaken idea that you intended to post with a basic sense of courtesy.
Thanks. That was helpful.
Hidden 'I' is subject here. and thank you is predicate and you is also object.
Note that you are posting to a thread that has not been active for nearly 10 years. The original participants are unlikely to read your post.
