Kills is not a part of leaderstats glitch?

It keeps telling me that Kills is not a valid member of Model "Players.MyName.leaderstats".

I know it is a valid member, so I dont know why this is happening. This is my leaderstats script:

local Players = game.Players

local Template = Instance.new("BoolValue")
Template.Name = "leaderstats"

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

Players.PlayerAdded:Connect(function(player)
    wait(1)
    local Stats = Template:Clone()
    Stats.Parent = player
    local Deaths = Stats.Deaths
    player.CharacterAdded:Connect(function(Character)
        Deaths.Value = Deaths.Value + 1
        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
                            Kills.Value = Kills.Value +1
                        end
                        return
                    end
                end
            end)
        end
    end)
end)

I don't think anythings wrong with that. This is the code that is not working:(it is in a textbutton and it is supposed to give a sword)

player = game.Players.LocalPlayer
backpack = player.Backpack
local plr = game.Players.LocalPlayer

plr:GetMouse().KeyDown:Connect(function(K)
    if K == "e" then
        local sword = game.Lighting.Tools.ClassicSword:Clone() ---- change "ClassicSword" to the name of your tool

        if player.leaderstats.Kills.Value >= 15 then ----- change 10 to the price of your tool and "Money" to whatever you named your Points for leaderboard
            player.leaderstats.Kills.Value = player.leaderstats.Kills.Value - 15 ----- change 10 to the price of your tool and "Money" to whatever you named your Points for leaderboard
            sword.Parent = backpack
        end
    end 
end)



plr:GetMouse().KeyDown:Connect(function(F)
    if F == "x" then
        game.StarterGui.ShopGui.Shop.Visible = false
    end
end)

I also wanted it so x closes the shop gui. Why is my code not working? (e also opens the shop if that helps at all.) All help is appreciated.
