attemp to index a nil value (local 'i')

[IceG4merBR 0]

Got this error, but i have no idea how to fix it, need some help!.

Here is the code.

local component = require("component")
local term = require("term")
local gpu = component.gpu
local cube = component.basic_energy_cube
local event = require("event")
 
local colors = { black = 0x000000, red = 0xC14141}
 
gpu.setBackground(colors.black)
term.clear()
 
local infos = {}
 
cube["stats"] = {}
 
function setInfos()
  infos["stored"] = { x = 3, y = 2, weight = 73, height = 1, title = "STORED ENERGY : ", unit = " RF"}
  infos["capacity"] = { x = 3, y = 4, weight = 73, height = 1, title = "BATTERY CAPACITY : ", unit = " RF"}
end
 
function printInfos(infoName)
  local maxLenght = 15
  local i = infos[infoName]
  gpu.set(i.x, i.y, i.title .. cube.stats[infoName] .. i.unit)
end
 
function updateCubeStats()
  cube.stats["stored"] = cube.getEnergyStored
end
 
function startup()
  updateCubeStats()
  setInfos()
  printInfos()
end
 
startup()
 
repeat
  updateCubeStats()
until event.pull(0.1) == "interrupted"

infoName isnt assigned, you forgot to call printInfos with a string, something like printInfos("stored")

I got this error now.

Only changed the printInfos() in startup() to printInfos("stored")

local component = require("component")
local term = require("term")
local gpu = component.gpu
local cube = component.basic_energy_cube
local event = require("event")
 
local colors = { black = 0x000000, red = 0xC14141}
 
gpu.setBackground(colors.black)
term.clear()
 
local infos = {}
 
cube["stats"] = {}
 
function setInfos()
  infos["stored"] = { x = 3, y = 2, weight = 73, height = 1, title = "STORED ENERGY : ", unit = " RF"}
  infos["capacity"] = { x = 3, y = 4, weight = 73, height = 1, title = "BATTERY CAPACITY : ", unit = " RF"}
end
 
function printInfos(infoName)
  local maxLenght = 15
  local i = infos[infoName]
  gpu.set(i.x, i.y, i.title .. cube.stats[infoName] .. i.unit)
end
 
function updateCubeStats()
  cube.stats["stored"] = cube.getEnergyStored
end
 
function startup()
  updateCubeStats()
  setInfos()
  printInfos("stored")
end
 
startup()
 
repeat
  updateCubeStats()
until event.pull(0.1) == "interrupted"

I believe your error is coming from updateCubeStats().

cube.stats.stored = cube.getEnergyStored()

You're missing parentheses.
