Hi! Iv'e been working on a piece of software for an auto install program through disks.

I run the code as a startup from disk on reboot and I get the error "startup:126: bad argument: int expected, got nil"

Here's my code:




function os.pullEvent()
local cEvent, p1, p2, p3, p4, p5 = os.pullEventRaw()
if cEvent == "terminate" then
end
return cEvent, p1, p2, p3, p4, p5
end

function getCenterX(sText)
local nWidth = term.getSize()
local x = math.floor(nWidth / 2) - math.floor(string.len(sText) / 2)
end

function getCenterY()
local nWidth, nHeight = term.getSize()
local y = math.floor(nHeight / 2)
return y
end

function getRight(sText)
local nWidth = term.getSize()
local x = nWidth - string.len(sText)
return x + 1
end

function runMenu(mChoices, sMenuTitle)
local nSelection = 0
local bLoop = true

while bLoop == true do
term.clear()
term.setCursorPos(1,1)
print(sMenuTitle)
print()

for nLine = 0, #mChoices do
local sLine = " "
if nSelection == nLine then
sLine = "> "
end
sLine = sLine .. mChoices[nline]
print(sline)
end

local nWidth, nHeight = term.getSize()
local y = nHeight
local x = getRight("LNET Technologies")
term.setCursorPos(x, y)
term.write("LNET Technoligies")

local sEvent, nKey = os.pullEvent("key")

if nKey == 200 then
if mChoices[nSelection - 1] then
nSelection = nSelection - 1
end
elseif nKey == 208 then
if mChoices[nSelection + 1] then
nSelection = nSelection + 1
end
elseif nKey == 28 then
if mChoices[nSelection] then
bLoop = false
return nSelection
end
end
end
end

function menu()
repeat

if nMenuNum == 0 then
mChoices = {}
mActions = {}
mChoices[0] = "LNET Security Program"
mChoices[1] = "Cancel Setup"
mActions[0] = function() nMenuNum = 1 end
mActions[1] = function()
term.clear()
local x = getCenterX("Cancelling Setup")
local y = getCenterY()
term.setCursorPos(x, y)
term.write("Cancelling Setup")
local x = getCenterX("Please wait….")
term.setCursorPos(x, y + 1)
term.write("Please wait….")
local nWidth, nHeight = term.getSize()
local y = nHeight
local x = getRight("LNET Technologies")
term.setCursorPos(x, y)
term.write("LNET Technologies")
sleep(3)
os.shutdown()
end
local nSelection = runMenu(mChoices, "LNET Technologies")
mActions[nSelection]()
elseif nMenuNum == 1 then
mChoices = {}
mActions = {}
mChoices[0] = "LNEX Security System"
mChoices[1] = "Return"
mActions[0] = function() nMenuNum = 2 sVersion = "Client" end
mActions[1] = function() nMenuNum = 0 end
local nSelection = runMenu(mChoices, "Choose your version")
mActions[nSelection]()
elseif nMenuNum == 2 then
mChoices = {}
mActions = {}
mChoices[0] = "Install"
mChoices[1] = "Skip"
mChoices[2] = "Return"
mActions[0] = function() bMenuLoop = false bLogPref = true end

try this

I found what was wrong but with the same code only fixed a new problem arises… attempt to index? (a nil value)

Code:


function os.pullEvent()
local cEvent, p1, p2, p3, p4, p5 = os.pullEventRaw()
  if cEvent == "terminate" then
  end
return cEvent, p1, p2, p3, p4, p5
end
function getCenterX(sText)
local nWidth = term.getSize()
local x = math.floor(nWidth / 2) - math.floor(string.len(sText) / 2)
return x
end
function getCenterY()
local nWidth, nHeight = term.getSize()
local y = math.floor(nHeight / 2)
return y
end
function getRight(sText)
local nWidth = term.getSize()
local x = nWidth - string.len(sText)
return x + 1
end
function runMenu(mChoices, sMenuTitle)
local nSelection = 0
local bLoop = true

while bLoop == true do
  term.clear()
  term.setCursorPos(1, 1)
  print(sMenuTitle)
  print()

  for nLine = 0, #mChoices do
   local sLine = "  "
   if nSelection == nLine then
    sLine = "> "
   end
   sLine = sLine .. mChoices[nLine]
   print(sLine)
  end
 
  local nWidth, nHeight = term.getSize()
  local y = nHeight
  local x = getRight("LNET Technologies")
  term.setCursorPos(x, y)
  term.write("LNET Technologies")
 
  local sEvent, nKey = os.pullEvent("key")
 
  if nKey == 200 then
   if tChoices[nSelection - 1] then
