Hi folks,
Like the title says, I'm confused about chests and how to lock them with a combo lock. I've gone through the tutorials, but cannot make it work. I get to the point where I have the combo lock placed, the chest placed, and I know how to set or change the combo on the combo lock. BUT, how do I make the lock actually lock the chest? How do I make it so the chest opens when the lock is solved?

I'm very frustrated as I've been trying several days and I've figured out just about everything else with no problem. I'm missing something obvious.

Thanks!
