Please explain what isn't working. As for each unit spawning three times, which system are you using? If you're using the second one I explained, then try the first one.
Also, make sure you have it under ONE player, not the forces. If it still doesn't work, have a new trigger.

Set Switch 1
Then add the condition "Switch 1 is Set" to your Bunker triggers. This should help.
Ultraviolet -- Inf, we've got a job for you. ASUS has been very naughty and we need our lil guy to go do their mom's to teach them if they fuck around, they gon' find out
UndeadStar -- I wonder if that's what happened to me. A returned product (screen) was "officially lost" for a while before being found and refunded. Maybe it would have remained "lost" if I didn't communicate?
