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.
