could someone help me out with this script\editing

[Theforgot3n1]

In case you might want to understand yourself, or you're unable to get help from a builder, I can tell you that it's an awful lot easier to script and built the elevator than you'd think.
Open the "elevator.hps" in "redist" > "maps" > "Ch1", and the level editor map - you might learn to script it yourself.

It works with one function similarly to the metal vet (elevators) in Cistern Entrance.
