Thanks, Don, for the explanation. No, I don't understand a lot of what you wrote, but I think it's due to me not understanding Indices and perhaps counting in general as well as that sometimes I just don't understand even simple things due to maybe focusing on the wrong thing or overthinking ("Overkill") or whatnot.

Thanks again for the answers. I believe what you wrote isn't wasted on me because many others will benefit from it.
