Mapping FX Focus Help

I have a midi fighter and I'm trying to get the 4th FX unit to focus similar to FX units 2 and 3 when pressing "Shift" and "Play/Pause" to shift the FX focus from deck to deck... I somehow managed to get it to turn on FX unit 4 on the deck it leaves and turn off FX unit 4 on the deck it focuses to instead of the reverse.

Anyone have any idea how to do this? I really have no clue as I have pretty much no midi mapping experience.

Thanks in advance.

Bump. Nobody knows how to solve this? I still can't get it to work.

I think we'd need a little more information about your mapping to help out. If it's doing the opposite of what you want, however, shouldn't it be a simple matter of checking the 'invert' button on your button, or reversing your modifier conditions (if you're using them)?
