saving variable for trap deactivated by button panel

hi I have some electric traps that are deactivated by a button panel(which I think is a child actor of the trap , or is attached to it. I am trying to figure out what variable to save so after saving game each trap will remain deactivated for whatever ones the button was pushed. any ideas?theres some variables in the trap bp that might work, but when I go to the savegame bp those variables don’t show up in the search after add variable. how would I add the variable from the trap bp to the savegame bp? thanks
