Here’s My Code:

local Items = require(game:GetService("ReplicatedStorage"):WaitForChild("Items"))

function module:GetRandomItem(Player)
	local Rarity = RandomRarityFunc.PickRandom()
	--Just Returns a Random Rarity like "Common", "Uncommon", "Epic", etc

	local function Length(Table)
		local Counter = 0
		for i, v in pairs(Table) do
			Counter = Counter + 1
		end
		return Counter
	end
	
	local ItemsOfRarity = {}
	
	for i = 1, Length(Items) do
		print(Items)
		if Items[i].Rarity == Rarity then
			table.insert(ItemsOfRarity, Items[i])
		end
	end		
        local RandNum = math.random(1, #ItemsOfRarity)
	
	local Data = {}
	table.insert(Data, ItemsOfRarity[RandNum])
	table.insert(Data, Rarity)
	
	return Data
end

I am a New Developer (Exp:11 Months) and I am making a Random Item Giving System based on Rarity. This is a small part of that code inside a Module Script. For some reason this Code Dosen’t Work.

Item[1] shows nil when trying to print.

Btw, here’s how the Items module looks like. Its Unfinished

You’re using string indexes inside your items module ([“Banana Peel”] = …), and trying to access it with number indexes, instead of doing for i = 1, Length(Items) do, you will want to do

for itemName, itemData in pairs(Items) do
	if itemData.Rarity == Rarity then
		table.insert(ItemsOfRarity, itemData)
	end
end

I wanted to return the key as a string to use it in another script but this code is returning a table. I was using a code very similar to this one and somehow it was returning strings not tables.
