Help me optimize this program/laugh at my mistakes?

  numpan = 1
  end

local side = "right" -- which side is the monitor on?
local m = peripheral.wrap(side)
m.setTextScale(size)

--ingredients times the number of panels wanted.

local norm1 = numpan -- I realize this isn't necessary, however when I was filling out the code,
--I had numbers in place of how many each panel needed, so it was easier to just write "norm"

Also, why do I have to use one "=" for lines one and two, and two for line three? Is it because I'm specifying a string instead of a number?
