Didn't test but should work.
Something like this:
button_trig is the targetname of the triggers
button_door -targetname of the doors (!!!script models/brushmodels!!!)
buttons = GetEntArray("button_trig","targetname");
well the launcher says it cant find zm_perk_electric_cherry which means there isnt a #using electric cherry in the script.
If after adding this, linking and starting the game you get a console error, you also need to put it in the zone
