Multiple Lookups not working properly

[m_rogoff]

I have attached a block. It has options to turn the track on/off at the top & bottom (the track is magenta "U" with yellow screws. These are controlled by the pull down menus between the green vertical lines). Idealy, I'd be able to toggle on/off independely of each other, or select both on or both off.

Right now, as it functions, if the top is turned on and you turn on the bottom, the top turns off. I have explored the option of just using one pull down menu (both off, top on, bott on, both on) but it's hard to keep track of top/bottom when it's rotated horizontally. Please let me know if I need to clarify more.

Help and suggestions are much apprectiated, thanks!

In considering the various states, and what the corresponding lookup values are, I can see how the issues arise.  At this point you want both ends to be independent AND dependent and it's a challenge to sort the logic.  You can easily sort the issues with the logic by have just the options of ON and OFF at each end or by having Both ON, Both OFF, ThisON/ThatOFF, ThisOFF/ThatON for each end.  See attached which has both examples.

Thank you Libbya. I think I'm going to use the This On/That Off option
