I recently asked a question that seemed to be quite difficult to answer. I got only one answer, which I approved because it seemed to do exactly what I wanted it to do. When I later started experimenting it turned out that it doesn't work as well as I thought. Now I have a bunch of new questions connected to that answer if it's ever to work. I asked them to the original answerer, but I think I'm having too long discussions in the comments for this site's liking and I can't open a chat because I don't have enough reputation. How should I proceed? I don't want to spam the same question. What should I do in the more general case of there being no answers?
