Trying to pull lists of items from chest

[DrStein]

I'm trying to get a list of items that are in the chest using .GetItemMeta(). Specifically I'm trying to print the Slot, Display Name and Itemcount to the right monitor. I get an error when attempting to run the code

Code Select Expand

test.lua:7: attempt to concatenate field 'count' (a nil value)
Below is the full code I'm trying to run

Code Select Expand

monitor = peripheral.wrap("right")
chest = peripheral.wrap("left")
y = 1

for slot, item in pairs(chest.getItemMeta(y)) do
  monitor.setCursorPos(1, y)
  monitor.write(y .. " " .. item.displayName .. " " .. item.count)
  y = y + 1
end

Any help would be greatly appreciated :)

[pjals]

monitor.write(y .. " " .. item.displayName .. " " .. item.count)

replace

Code Select Expand

monitor.write(y .. " " .. item.displayName .. " " .. item.count) with

Code Select Expand

monitor.write(y .. " " .. item.displayName .. " " .. item.count or 1)

That won't work - you'd need to do (item.count or 1). However, this whole thing is a bit strange - count should never be missing. It might be worth doing print(textutils.serialize(item)), and seeing what properties it has.
