How To Get Exp When A Humanoid Dies?

I've had 2 of this same questions in different forums and no one can figure why it doesn't work. I have a basic roblox dummy in the workspace and it has a humanoid and everything. So When I Kill the Dummy the GiveExp Script says {xp is not a valid member of Folder}, here is the scripts.

----Leaderstats Script(Normal Script)----

game.Players.PlayerAdded:Connect(function(plr)
    local leaderstats = Instance.new("Folder")
    leaderstats.Parent = plr
    leaderstats.Name = "Leaderstats"

        local lvl = Instance.new("IntValue")
        lvl.Parent = leaderstats
        lvl.Name = "Level"

        local xp = Instance.new("IntValue")
        xp.Parent = leaderstats
        xp.Name = "Exp"

   end)

----GiveExp Script (Normal Script)----

local leaderstats = game.Players.LocalPlayer:WaitForChild("Leaderstats")

game.Workspace.Dummy.Humanoid.Died:Connect(function()
            leaderstats.Exp.Value = leaderstats.xp.Value + 10000
       end)

I've have asked this so many times and no brilliant mind can figure this out, could somebody take the time to help this old lad?
