So I am trying to make the R15 persone to R6 I tried everything but here the user's Motor6Ds Auto destroy

script.Parent.MouseButton1Click:Connect(function()
	local chr = script.Parent.Parent.Parent.Parent.Character --user's character
	chr.Humanoid.RequiresNeck = false	--letting them stay alive
	chr.Humanoid.RigType=Enum.HumanoidRigType.R6  --making their Humanoid Need R6 Parts
	for i,v in pairs(chr:GetChildren()) do
		if v:isA("MeshPart") or v:isA("Part") then
			v:Destroy()            --Destroying all R15 Parts including head and HumanoidRootPart
		end
	end
	for i,v in pairs(game.Workspace.r6:GetChildren()) do
		if v:isA("Part") then
			v.Parent=chr                       --Moving in the R6 parts
		end
	end
	chr.Humanoid.RequiresNeck = true    --making them alive
	local x = 0
	while x~=100 do
		wait(.1)
		chr.Humanoid.Health=100    --trying despretly to revive them
		x=x+1
	end
end)
