My "Pick Up Player" script works perfectly the first time. But is random the other times?

My script is supposed to pick up the player/ put them above you and weld them there. And it works the first time. Yet after the first time. Something happens and it will still go above the players head. But not at the same X and Z. it'll still be welded to you and move when you move. But it will be like 15 studs in front of you and 4 studs to the side. How do i fix this?

Script:

local event = game.ReplicatedStorage.KillPlayer

event.OnServerEvent:Connect(function(Player, FromP, ToP)
	local RayCast = Ray.new(FromP, (ToP-FromP).unit*100)
	local part = game.Workspace:FindPartOnRay(RayCast, Player.Character, false, true)
	if part then
		local char = part.Parent
		local Hum = char.Humanoid
		if Hum then
			if not char:FindFirstChild("Weld") then
				Hum.PlatformStand = true
				char.HumanoidRootPart.CFrame = Player.Character.HumanoidRootPart.CFrame + Vector3.new(0, 3, 0)
				local weld = Instance.new("Weld", char)
				weld.Part0 = char.HumanoidRootPart
				weld.Part1 = Player.Character.HumanoidRootPart
				weld.C0 = char.HumanoidRootPart.CFrame:inverse()
				weld.C1 = Player.Character.HumanoidRootPart.CFrame:inverse()
			else
				 char:FindFirstChild("Weld"):Destroy()
			end
		end
	end
end)

local script (So you can test it out and see what i mean)

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local Event = game.ReplicatedStorage.KillPlayer

mouse.Button1Down:Connect(function()
	Event:FireServer(player.Character:FindFirstChild("HumanoidRootPart").Position, mouse.Hit.Position)
end)

How do I fix this?

Edit: Just figured out it doesnt work that well onn the first run either.

I figured it out. I just changed the CFrame to Position. Still a bit glitchy but much better
