Issues with datastores, maybe due to pcall?

Hello! Im trying to save player data, and am having issues with saving it. It doesn't run the pcalls at all, and wondered if im missing something?

local dss = game:GetService("DataStoreService")
local ds = dss:GetDataStore("PlayerStatistics")

game.Players.PlayerAdded:Connect(function(player)
    print("PlayerAdded")
    local Statistics = Instance.new("Folder", player); Statistics.Name = "Statistics"
    local Money = Instance.new("IntValue", Statistics); Money.Name = "Money" 
    local Population = Instance.new("IntValue", Statistics); Population.Name = "Population" 
    local Souls = Instance.new("IntValue", Statistics); Souls.Name = "Souls" 

    local MoneyLoaded
    local PopulationLoaded
    local SoulsLoaded
    local success, errormessage = pcall(function()
        MoneyLoaded = ds:GetAsync(player.UserId.."-money")
        PopulationLoaded = ds:GetAsync(player.UserId.."-population")
        SoulsLoaded = ds:GetAsync(player.UserId.."-souls")
    end)        
    if success then
        Money.Value = MoneyLoaded
        Population.Value = PopulationLoaded
        Souls.Value = SoulsLoaded
        print(player.Statistics.Money.Value)
        print(player.Statistics.Population.Value)
        print(player.Statistics.Souls.Value)
    else
        print("Error occured during data get")
        warn(errormessage)
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    print("PlayerRemoved")
    local success, errormessage = pcall(function()
        ds:SetAsync(player.UserId.."-money", player.Statistics.Money.value)
        ds:SetAsync(player.UserId.."-population", player.Statistics.Population.value)
        ds:SetAsync(player.UserId.."-souls", player.Statistics.Souls.value)
        print(player.Statistics.Money.Value)
        print(player.Statistics.Population.Value)
        print(player.Statistics.Souls.Value)
    end)

    if success then
        print("Data saved successfully")
    else
        print("An error occured")
        warn(errormessage)
    end
end)
