Players:vxcaie.Backpack.Energy.Script:1: attempting to index nil with 'leaderstats"?

So when I tried finding the leaderstats so I could earn some points for my stats, this error appeared: "Players:vxcaie.Backpack.Energy.Script:1: attempting to index nil with 'leaderstats"

Note: It says "vxcaie" because i actually changed my username recently so it doesn't say vxcaie in this website.

Script:

energyamt = game.Players.LocalPlayer.leaderstats.Power
db = true
script.Parent.Activated:Connect(function()
	if db == false then
		db = true
		energyamt.Value  = energyamt.Value + 1
		db = false
		wait(2)
	end
end)
