This was so helpful, thank you so much I've really been struggling. I was wondering if you could explain the sub chain{} function? I'm not at all sure what you're doing there, but it works! Also do you have any advice as to what I should do if I want to remove the first row so the header doesn't do what the rest of the hash is doing. Again, really appreciate all your help.
