Thank you Ethan, It has worked!

I think you should familiarize yourself more with data-matching, or else you’re going to encounter problems like this over and over. Hover over the inputs to Dispatch and you’ll see that there are the same number of branches now going in both. That’s what you should strive for.

Yes, data matching is heart of gh maybe, thank you for your tip and suggestion. I am going to try it. Cheers.
