Learning my way through making toggles but it's not working right?

I made a toggle for a necklace object. When I hit the toggle (in-game) it correctly enables it, but then when I hit toggle again to turn it off it just stays on, it doesn't turn off the necklace?

In the fx layer I set up with the default state being called "OFF" and has no motion, then transitions to the "turn on necklace" animation when necklace parameter=true, then transitions back to the off state when the param=false. What could I be doing wrong that isn't making it turn off when I hit the toggle again?
