Ah, yes. I am a noob when it comes to Lua, so if there is a very simple and obvious solution to this problem let me apologize in advance.
Alright, here is the problem: I have this mod Thut's Elevators installed so you can make realistically working elevators in Minecraft. I have this program to control the elevator through buttons on a tier 2 screen. But due to how the mod is made you can't have a screen on board in the elevator, so I need to have a screen on each new elevator destination. The buttons are working and can send the elevator from one screen, but I can't switch it to another
