OK, I'm being thick headed tonight - there has to be an elegant way to do this, and all I can think of is a mess of brute force ugliness. I have 8 umenu objects, each containing identical elements of "--" followed by integers 1 through 16. If you select one of the integers 1 through 16, it should set any existing umenu that was set to that value back to the "--" entry. Basically these are MIDI channel selectors, and I want to be able to only allow a MIDI channel to be selected once. Here's the eight umenus - oh, and please no 3rd party objects, built in Max objects only!

Thanks for giving it a shot - but it's not the behavior I was looking for. Yours only allows one umenu to have a MIDI channel selected at any time. What I desire is to allow any of the umenu objects to have an integer selected, *SO LONG AS NO OTHER UMENU HAS IT ALREADY SELECTED*. Choosing an integer that another umenu already has selected should in turn revert that other umenu item to the 0 entry, or "--".

I was really thinking that something using [zl sub] was the way to go, but several attempts didn't work...

Perfect, you nailed it Broc! And I see that you used zl sub after all....
