What is wrong with this script that saves a players stages?

i made a script that is supposed to save a players stage when they leave the game. for some reason the script will not work this is the script:

local players = game:GetService("Players") local dataStoreService = game:GetService("DataStoreService") local saveDataStore = dataStoreService:GetDataStore("SaveDataTest")

local function saveplrData(plr)

local succes,err = pcall (function()

	local saveData = {}
	for _,stats in pairs (plr.leaderstats:GetChildren()) do
		
		
		saveData[stats.Name] = stats.Value
		
	end
	
	saveDataStore:SetAsync(plr.UserId,saveData)

end)

if not succes then return err end

end

players.PlayerAdded:connect(function(plr)

local stats = Instance.new("Folder")
stats.Name = "leaderstats"
stats.Parent = plr

local stage = Instance.new("IntValue")
stage.Name = "Stage"
stage.Parent = stats

local data = saveDataStore:GetAsync(plr.UserId)

if data then
	
	print(data.Stage)
	
	for _,stat in pairs (stats:GetChildren()) do
		
		stat.Value = data[stat.Name]
		
	end
	
else
		
		print(plr.Name .. " has no data")
	
end

plr.CharecterAdded:connect(function()
	
	local humanoid,hrp = char:WaitForChild("Humanoid"),char:WaitForChild("HumanoidRootPart")
	
	wait()
	
	if humanoid and hrp then
		
		if stage.Value ~= 0 then
			
			local part = workspace.ObbyStages:FindFirstChild(Stage.Value)
			hrp.CFrame = part.CFrame + Vector3.new(0,1,0)
			
		end
	end
	
end

end)

players.PlayerRemoving:connect(function(plr)

local err = savePlrData(plr)

if err then print(err) end

end)

game:BindToClose(function()

	for_,plr in pairs (players:GetPlayers()) do	
		
		local err = savePlrData(plr)
		
		if err then print(err) end
		
	end

wait(2)

end)

I think this is the problem, u cant insert in a table like that ill show u how

local succes,err = pcall (function()
local saveData = {}
   
    for _,stats in pairs (plr.leaderstats:GetChildren()) do
 

        table.insert(SaveData, stats.Name, stats.Value)

    end

    saveDataStore:SetAsync(plr.UserId,saveData)

end)

if not succes then return err end
