why wont it add points to the leader stats?

this script is to pick up a coin and to add a point on the leader stats but it won't let me add the points to the leader stats.

local coin = script.Parent

function ont(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		Points.Value = Points.Value + 1
		coin:Destroy()
	end
end

game.Workspace.Part.Touched:connect(ont)

You never defined Points.

local coin = script.Parent

function ont(hit)
	local player = hit.Parent and game:GetService('Players'):GetPlayerFromCharacter(hit.Parent)
	local ls = player and player:FindFirstChild('leaderstats')
	local points = ls and ls:FindFirstChild('Points')
	
	if points ~= nil then
		points.Value = points.Value + 1
		coin:Destroy()
	end
end

workspace.Part.Touched:connect(ont)

Not sure if anything was defined, give this a shot? Added a debounce so there's a cooldown, feel free to remove this if you please.

local db = false
workspace.Part.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
		local stats = plr:FindFirstChild("leaderstats")
		if not db then
			db = true
			stats.Points.Value = Points.Value + 1
			wait(3)
			db = false
		end
	end
end)
