No violation that I know of. The original poster probably deleted the topic and it took all the replies with it. I’ve seen it happen before a few times. I guess this forum allows that but it always irks me a bit. We go out of our way to post a working solution to a problem and they get selfish and delete the topic after they get it. The solution was meant to help them, sure, but it’s also for the benefit of anyone else browsing the forum.
That's too bad, I wanted to see your solution.
I came up with another option today via the tree branch calculation method.
Looks like we need to move on, that's the way of the world.
