Multi-Floor Elevator

Hey everyone! This is a 9 floor smp friendly elevator that can take you up or down to any floor, starting from any floor. As far as I have seen, this is the most compact of its kind taking up 16*10 blocks worth of horizontal room. Because I had designed this for 7 meter tall rooms with 1 meter thick ceilings, that is what the elevator is built for. You can take the concept and expand it if you wish, and in the unlikely chance that someone builds this in a video of some sort, please give me (DrPhaedrus) credit. Instructions are included in a chest right when you spawn in. Thanks for looking at it and I hope you enjoy!
