Why isn't my table in DataStore saving?

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("coinsDataStore")

game.Players.PlayerAdded:Connect(function(plr)
	local data
	local success,errormessage = pcall(function()
		data = DataStore:GetAsync(plr.UserId.."-data")
		if data then
		else
				data = {0,1}
		end
		print("Got data")
	end)
	
	if success then
		print("Yay")
	else
		print(errormessage)
	end
	local leaderstats = Instance.new("Folder",plr)
	leaderstats.Name = "leaderstats"
	
	local checkpoints = Instance.new("IntValue",leaderstats)
	checkpoints.Name = "Stage"
	if data[2] then
	checkpoints.Value = data[2]
	else
		checkpoints.Value = 1
	end
	local coins = Instance.new("IntValue",leaderstats)
	coins.Name = "Coins"
	if data[2] then
	coins.Value = data[1]
	else
		coins.Value = 0
	end
	
	
	
		plr.CharacterAdded:Connect(function(Character)
		repeat wait() until plr.Character ~= nil	
		local checkpoint = workspace.Stages:FindFirstChild(checkpoints.Value)
		Character:WaitForChild("HumanoidRootPart").CFrame = CFrame.new(checkpoint.Position + Vector3.new(0,2,0))
	end)
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local id = plr.userId
	local checkpoints = plr.leaderstats.Stage.Value
	local coins = plr.leaderstats.Coins.Value
	local data = {coins,checkpoints}
	local success,errormessage = pcall(function()
		DataStore:SetAsync(plr.UserId.."-data",data)
	end)
	if success then
		print("Yay")
	else
			print(errormessage)
	end
end)

I am trying to get the datastore but it seems it doesn't load in. I have API services in Studio.
