Hello,

Can someone tell me or show me how to cross reference two buttons, or clips like they do here:

I’d imagine there are a lot of arrays involved. I’m just not sure how to get started…I would need everything to be dynamic…for I am doing a project very similar…I guess a better question would be how to do multiple relationships like this…
