Filtering Active Channel(s) from OSC Message

I currently have my box set up so that one encoder serves as my next/last buttons, one encoder is an intensity wheel, and my three buttons serve as palette selectors. All of that works great, except, I am having trouble getting my display to update with the current channel. I am trying to subscribe to the "/eos/out/active/chan" message, but I'm having a tough time interpreting if its working. I also am not sure how to parse the channel number from that OSCBundle. Kind of new to this, but I'm trying to learn quickly.
