How do I post a reply . . .

[Guest]

I clicked on "Quote" at the bottom of the post to which I wanted to reply.  I was taken to the bottom of that page to the "Reply to this topic" box.  I typed my response & clicked "Post."  My post appeared at the bottom of the last page without referencing the post to which I was referring, which made my comments idiotic without a point of reference.  What am I doing wrong?
