The secret door

[The Shanus]

Perhaps just use addforceprop or whatever function for it to move the shelf? That seems pretty simple - I dont see why it shouldnt work. What I don't understand is why you want a button, a lever, and a button straight after each other. It seems a bit pointless to me? A bit repetitive too. Just have a hidden button/ lever somewhere in the room which moves the shelves, and have the shelf move so that you can go to the door at the end, instead of having to do the same thing over and over.
