Bulletin Board scale issue

Hey dear fellow programmers,
I made this program for a bulletin board at my server, however, there is a slight issue with the code.
When set to textscale 2, it works fine, but the text is too big to fit on the screen. Using scale 1, however, will not print the most important parts of the board. It does not print the "layout", "header" and "info" parts, while it does actually print the line from "print1" when receiving the rednet message. I have no idea what causes this problem, so any help would be greatly appreciated!

Also, any tips on how to further improve this code are welcome as well!

Well, I don't think that would even run, because this function:

local function exit()
  break end

would throw an error (something like "nothing to break").

Actually, it doesn't, since I run the "exit" program in the "listen" loop, and only execute it when it receives the string "exit" through rednet.
The problem is that it doesn't print when on textscale 1, it does print on scale 2, but that doesn't fit…

No you don't, you call the exit function. If you try to run the program, it throws a "no loop to break" error.

Okay, in that case, I probably fixed this error in my latest version (playing on a server, so I don't have direct access to those files).
Anyway, this exit function is NOT the issue, I already finished the debugging shit, no more errorthrowing.
Again, my only issue is it not printing at scale 1. Only problem.

Well, without the actual working code, we can't help. There's no reason for the text to don't show with different text scale.
