How would I make this script load the 3 datas when a player dies but keep it for 3 new values?

local ds = game:GetService("DataStoreService"):GetDataStore("Level")
game.Players.PlayerAdded:connect(function(player)
    wait(player.CharacterAdded)
    local expvalue = player.ExpValue
    local gold = player.Gold
    local lvlvalue = player.LvlValue
    local expkey = 'expuser_'..(player.userId)
    local goldkey = 'golduser_'..(player.userId)
    local lvlkey = 'lvluser_'..(player.userId)
    expvalue.Value = ds:GetAsync(expkey)
    gold.Value = ds:GetAsync(goldkey)
    lvlvalue.Value = ds:GetAsync(lvlkey)
    if lvlvalue.Value == 0 or nil then lvlvalue.Value = lvlvalue.Value+1 end
    if gold.Value == 0 or nil then gold.Value = 1 wait(.1) gold.Value = 0 end
    if expvalue.Value == 0 or nil then expvalue.Value = 1 wait(.1) expvalue.Value = 0 end
    expvalue.Changed:connect(function()
        ds:SetAsync(expkey, (player.ExpValue.Value))
    end)
    gold.Changed:connect(function()
        ds:SetAsync(goldkey, (player.Gold.Value))
    end)
    lvlvalue.Changed:connect(function()
        ds:SetAsync(lvlkey, (player.LvlValue.Value))
    end)
end)
