HELP: trying to modify my first program to be more dynamic with peripherals

local cur0 = 0 -- variable for later use
local cur1 = 0 -- variable for later use
local pct0 = 0 -- variable for later use
local pct1 = 0 -- variable for later use
local overallPCT = 0 -- variable for later use
local max0 = c00.getMaxEnergyStored("unknown")  -- variable for finding the % of energy
local max1 = c01.getNaxEnergyStored("unknown")  -- see above

-- * Define functions

local function getStored() -- updates

cur0 = c00.getEnergyStored("unknown")
