Is this Datastore correct?

So I've been expanding on Datastores and was wondering if this is what a Datastore would look like if there was a LeaderStat that was called "Pizza"?

local store = game:GetService("DataStoreService"):GetOrderedDataStore("Star Shards")



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

player:WaitForDataReady()

local pKey = "plr_"..player.Name

local ls = Instance.new("IntValue", player)

ls.Name = "leaderstats"

local Pizza = Instance.new("IntValue", ls), Instance.new("IntValue", ls)

Pizza.Name = "Pizza"

local mode = Instance.new("BoolValue", player)

mode.Name, mode.Value = "playing", true

local wins = Instance.new("IntValue", ls)

Pizza.Name = "Pizza"

Pizza.Value = 0

Pizza.Value = 0

if store:GetAsync(pKey) ~= nil then

Pizza.Value = store:GetAsync(pKey)

else

Pizza.Value = 0

end

Pizza.Changed:connect(function(value)

store:SetAsync(pKey, value)

end)

end)
