How do you use an already existing leaderstat and not create a new one? (READ EDIT)

Most youtube tutorials on making stuff related to leaderstats, like a shop have them making a new leaderstat. The tutorial I followed was about making a trail shop, and the currency points. When you kill a player you are awarded a kill on the leaderstats and about 15 points. I want to use the leaderstat "Points," which is was created in the script where when you are awarded a kill and points when you kill someone (which I'll call Kill counter below). How do I not make another leaderstat called "Points?"

edit: Also if I create another "Points" leaderstat, it won't appear or it will appear but the "Kills" won't

edit2: Scrap the first edit, I just realized it was not a leaderstat. I will be making changes. For now it is solved.

Code for the "Kill counter"

local Players = game.Players

local Template = Instance.new 'BoolValue'
Template.Name = 'leaderstats'

Instance.new('IntValue', Template).Name = "Kills"
Instance.new ('IntValue', Template).Name = "Points"

Players.PlayerAdded:connect(function(Player)
    wait(1)
    local Stats = Template:Clone()
    Stats.Parent = Player
    Player.CharacterAdded:connect(function(Character)
        local Humanoid = Character:FindFirstChild "Humanoid"
        if Humanoid then
            Humanoid.Died:connect(function()
                for i, Child in pairs(Humanoid:GetChildren()) do
                    if Child:IsA('ObjectValue') and Child.Value and Child.Value:IsA('Player') then
                        local Killer = Child.Value
                        if Killer:FindFirstChild 'leaderstats' and Killer.leaderstats:FindFirstChild "Kills" then
                            local Kills = Killer.leaderstats.Kills
                            local Points = Killer.leaderstats.Points
                            Kills.Value = Kills.Value + 1
                            Points.Value = Points.Value + 15
                        end
                        return
                    end
                end
            end)
        end
    end)
end)

And for the script where I need to use the already made leaderstat.

Line 28 is the former problem.
