Your post is not attached to any other post, so what you are referring to is kind of missing. I think I get what it is you are referring to, however others might not.
Also, the main part of what you are saying should be in the body of the post, not the title. As it got cut off so it is impossible to know what you were planning to say. To reply to a post, just type in the box at the bottom of that posts thread, under where it says "Your answer" and then when you are done typing click the "Submit your answer" button under it. That will add the info to the thread you are referring to.
