I have a logical problem with io boxes. There are three io boxes. Two of them are recieving data. The third should display the data of the io box which is actually changing. I know when the data of box 1 or box 2 is changing, but how to tell box 3 wether to take its input from box 1 or box 2? I think I could use something like an “if” node, but can’t find one. Any tips or node suggestions?
