Trying to rotate something? An old Lua scripter

So, I am someone who scripted Lua in the old days, back when orientation was called rotation, so, when I tried to script something new, it isn't working, there is no error message in the output log. So, here is the script. Please help me figure out why it isn't working.

local function Swing()
	while true do
		for i=-30,-120,-2 do
			script.Parent.Orientation = Vector3.new(0,90,i)
			wait(0.01)
		end
		wait(2)
		for i=-120,-30,2 do
			script.Parent.Orientation = Vector3.new(0,90,i)
			wait(0.01)
		end
		wait(2)
	end
end

wait(2)
Swing()

Try using cframe*angles instead of orientation

Look up cframe*angles in the wiki it's an easy fix
