how would i add code to make my saving leaderboard increase the kill amount by 1 when i kill? [closed]

game.Players.PlayerAdded:connect(function(player)
local DataStore = game:GetService("DataStoreService")

     local leader = Instance.new("Folder",player)
leader.Name = "leaderstats"

for i,v in pairs(script:GetChildren()) do 
local d = DataStore:GetDataStore(v.Name)
local x = Instance.new("NumberValue",leader)
x.Name = v.Name
x.Value = d:GetAsync(player.UserId) or v.Value



end
end)

game.Players.PlayerRemoving:Connect(function(player)
    for i,v in pairs(script:GetChildren()) do 
        print("Getting")
        local DataStore = game:GetService("DataStoreService")
        local d = DataStore:GetDataStore(v.Name)
        d:SetAsync(player.UserId, player.leaderstats[v.Name].Value)
        print("Saved")
    end
end)

the intvalue for the stats was put inside the script
