Problem with Data Store?

I am trying to save player.Codes.Roy.Value, Codes is a folder I put into player, what could the problem be, why is this not saving and/or loading?

On Player Added

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

game.Players.PlayerAdded:connect(function(player)

    local key = "player-"..player.userId

    local savedValues = DataStore:GetAsync(key)

    if savedValues then
        player.Codes.Roy.Value = savedValues[1]
    else
        local valuesToSave = {player.Codes.Roy.Value}
        DataStore:SetAsync(key, valuesToSave)
        print("Data Loaded")
    end

end)

On Player Leaving

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

game.Players.PlayerRemoving:connect(function(player)

    local key = "player-"..player.userId

    local valuesToSave = {player.Codes.Roy.Value}
    DataStore:SetAsync(key, valuesToSave)
    print("Data Saved")
end)
