Why doesn't the lift tutorial on the UE4 wiki work in 4.7?

Hi
I’ve tried 3 times to do the lift tutorial on the official documentation site for UE4 and it doesn’t work. Never has.
Video tutorials that i’ve followed to the letter don’t work. I’ve got a default 3rd person game, new level, the matinee works, but when I play the game it doesn’t work.

Why doesn’t it work!?!? It is driving me insane!
Please send help

Or coffee

Thanks in advance

Have you tried this one.

Just did , and it’s working now thanks. Would the lift/trigger being inside a static mesh’s collision box prevent it from working?

Should not, using a normal bp to do the work should work.
