Matching OSC input in Max patch

I need some help as I’m stuck with trying to match an incoming OSC message to trigger an event. It’s probably quite simple, but I’m a beginner.

The incoming OSC message sends the zone number, user number and 0 or 1 if the zone is activated/deactivated. e.g. zone_1 1 0

I need to change the zone number for each instance of the patcher. I don’t need the user info, but if it is needed in the sequence, then anything between 1 and 20 will create a match. I need to toggle on /off using the last element in the message (0/1) if the zone number is matched.

I’ve put the rough outline of what I need in a patch, but I’m not sure I should be using zl slice and match, or how to get a combination of variables and non-variables to match. I would appreciate some guidance very much!

Here is an approach that should work:
