Label your elevator with whatever name you like.
Download the tool in the guide above, and add execute functions to your switches' trigger.
Use GoUp or GoDown in the execute function and reference the name of your elevator.

Its way less complicated then it sounds.
Place switch - place elevator - name elevator - save - close game - use tool - start game - use execute function in switch trigger to command elevator (GoDown/GoUp)
Done.

Random Triggers are difficult to pull off, as it requires a lot of variable manipulation. My Elevator Action level I used the enemy death frequency, so the elevators move whenever someone is killed.That way it feels both random and controlled.

Damn that link almost gave me a virus. Is there another place where i can download it.

Oo?
Its a standard uploaded.net upload....
You click "Free Download" - Wait 30 seconds - Enter a Captcha - File download starts itself (should be "Broforce Tool.zip")

Tbh i dunno if there are any popups because i have ad block plus... you should get that by the way, like, in general :D

yeah i got this strange setup.zip file (no pop-up thanks to my sturdy ad block ;) ) but still they almost tricked me thank got i've got hitman pro on my side to back me up almost lost all my files .... :/ oohwell

Oo
Yeah it should not be a setup...
