I'm brand new at this, and don't know what I'm doing wrong. I recreated the door to my shed into 3-linked parts, then C&Ped this script from "default" to the bottom in it's entirety as a new script in the wall next to the "DOOR".
When I got to "Save" - I did that, and then linked the parts together starting with the roof, and ending with the floor, and the door was somewhere in between - so I'd remember not to do it last.
Then I tested the door by 'touching' the wall with the included script.... didn't work.
Where'd I mess up?
