"attempt to index number with number" Datastore tables

Hello, I am trying to code a data store that saves multiple data in a table, but apparently, it pops up with the error;
“attempt to index number with number”.





local Service = game:GetService("DataStoreService")
local Key = Service:GetDataStore("LyfeDataStore_1")

game.Players.PlayerAdded:Connect(function(plr)
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Parent = plr
	leaderstats.Name = "leaderstats"
	local val = Instance.new("IntValue")
	val.Parent = plr
	val.Name = "Cash"
	
	local data
	local success, result = pcall(function()
		data = Key:GetAsync(plr.UserId)
	end)
	
	if success then
		-- SUCCESS
		if data then
			val.Value = data[1]
			plr:FindFirstChild("leaderstats"):FindFirstChild("Age").Value = data[2]
		end
	else
		warn("ERROR")
		error(result)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	
	
	local data = {plr:FindFirstChild("leaderstats"):FindFirstChild("Cash"), plr:FindFirstChild("leaderstats"):FindFirstChild("Age")}
	
	local success, result = pcall(function()
		Key:SetAsync(plr.UserId, data)
	end)
	
	if not success then
		warn("ERROR")
		warn(result)
	end
end)

Any ideas?

can you tell me which line the error occurs

Also, AFAIK you need to store tables after converting it into JSON when using datastores.
Use HTTPservice,

local jsonString = HTTPService:JSONEncode(data)

store the JSON string in the datastore. When retrieving the data, decode it with

local dataTable = HTTPService:JSONDecode(jsonString)

I’d say try printing data and see what comes back. I’m pretty sure you can use data stores with arrays/tables

You’re only retrieving the Instance of the data variable, not the Instance.Value

If you want the values to save, consider saving their Value properties instead of the Instance of it

Also, don’t call FindFirstChild whenever you’re trying to find a leaderstat value as soon as a player joins (You should always create it yourself in that same exact script, or call WaitForChild() instead)

local Service = game:GetService("DataStoreService")
local Players = game:GetService("Players")

local Key = Service:GetDataStore("LyfeDataStore_1")

Players.PlayerAdded:Connect(function(plr)
	
	local leaderstats = Instance.new("Folder")
	leaderstats.Parent = plr
	leaderstats.Name = "leaderstats"
	
	local Age = Instance.new("IntValue")
	Age.Name = "Age"
	Age.Parent = plr
	
	local val = Instance.new("IntValue")
	val.Name = "Cash"
	val.Parent = plr

	local data
	local success, result = pcall(function()
		data = Key:GetAsync(plr.UserId)
	end)
	
	if success then
		-- SUCCESS
		if data then
			val.Value = data[1]
			Age.Value = data[2]
		end
	else
		warn("ERROR")
		error(result)
	end
end)

Players.PlayerRemoving:Connect(function(plr)
	
	local leaderstats = plr:WaitForChild("leaderstats")
	local Cash = leaderstats:WaitForChild("Cash")
	local Age = leaderstats:WaitForChild("Age")
	
	local data = {
	    Cash.Value,
		Age.Value
	}
	
	local success, result = pcall(function()
		Key:SetAsync(plr.UserId, data)
	end)
	
	if not success then
		warn("ERROR")
		warn(result)
	end
end)

Thank you! It works,
The data now saves.

p.s

(p.s: I did put Cash.Value and Age.Value in the tables before, but it did not work, probably it was the spacing of the { and }?)

Sometimes it’s better to yield for trying to find these values rather than just “assuming” that they’re already in your Player, as worst case scenario it returns back an error

Both SetAsync and GetAsync are yielding functions, and won’t continue until a result is made inside those pcall functions

If you’re trying to call FindFirstChild while you’re still creating the Age variable somewhere else without any sanity checks, it might result back as an error hence why you’re assuming that the leaderstats, and the Age names are already there
