How to add kills to leaderstats with currency?

Here is the death and currency script

game.Players.PlayerAdded:connect(function(player)
 local folder = Instance.new("Folder", player)
 folder.Name = "leaderstats"
 local currency1 = Instance.new("IntValue", folder)
 currency1.Name = "Money"
 local DeathCount = Instance.new("IntValue", folder)
 DeathCount.Name = Deaths
 player.CharacterAdded:connect(function(character)
  character:WaitForChild("Humanoid").Died:connect(function()
  local tag = character.Humanoid:FindFirstChild("creator")
   if tag ~= nil then
    if tag.Value ~= nil then
     currency1.Value = currency1.Value + 100 --This is the reward after the player died.
     DeathCount.Value = DeathCount.Value + 1
    end
   end
  end)
 end)
end)

Hope this helps! Sorry I could not make a kill stat.
