@offthelip - A big thanks, endless loop no more, I was able to process the entire sheet. I now need to check the connections and apply more logic to see if they actually connect to each other. The heavy lifting is done.
@Sam - A simple logic was that I start using the TO and then use it match the FROM, then do it all over again. I thank you for your time looking into it. I think offthelip's solution is what I am after. I just need to do more checking.
