Attempt to get length of nil value error

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    A Module script for different rarities in a hatching system
  2. What is the issue? Include screenshots / videos if possible!
    it says attempt to get the length of nil value
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    i tried changing the brakets and checking it over but nothing its happening
    After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
local Avgmodule = {}

local AvgList = game.ReplicatedStorage.AvgPets
-- Put each pet to rarity
Avgmodule.items = {
	
	
	["Special"] = {
		AvgList["Big Boi"]
	};
	
	["Legendary"] = {
		AvgList["sus sus"]
	};
	
	["Rare"] = {
		AvgList["kinda sus] , AvgList["Little bit of salami"]
	};
	
	["Common"] = {
		AvgList["small morsel of salami"] , AvgList["sqauare"]
	};	
}
-- set rarity weights
Avgmodule.rarities = {
	
	["Special"] = 1;
	
	["Legendary"] = 5;
	
	["Rare"] = 30;
	
	["Common00"] = 64;
	
}

--Function of choosing pet
Avgmodule.RandomPet = function()
	local Ranum = math.random(1, 100)
	local counter = 0 
	for rarity, weight in pairs(Avgmodule.rarities) do 
		counter = counter + weight
		if Ranum <= counter then
			local raritytable = Avgmodule.items[rarity]
			local choosenitem = raritytable[math.random(1, #raritytable)] --where the error is coming from
			
			return choosenitem
		end
	end
end



return Avgmodule

*some context: Avg is an abbv for Average like this is an Average egg but some stuff may still be named with “pet” because I was remaking a script from AlvinBlox
Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.

You have not defined “raritytable” anywhere in the script. Did you forget to rename something or did you forget a line?

yeah i did right above the error

["Common00"]

The problem may be that Common has two 0s (zeroes) after it. Try changing it to just Common so that it lines up with the other table correct
