How do I make this old, broken dance tool work again?

There's this old dance tool that used to be popular on ROBLOX back in 2009. I wanted to use, but when I click it, nothing happens. What is wrong with this script?

function dance()

local me = script.Parent.Parent.Parent.Character.Torso

local RightShoulder = me["Right Shoulder"]
local LeftShoulder = me["Left Shoulder"]
local RightHip = me["Right Hip"]
local LeftHip = me["Left Hip"]

script.Parent.Sound:Play()

for i=1, 9 do 

	for i=1, 15 do

RightShoulder.MaxVelocity = 0.35
LeftShoulder.MaxVelocity = 0.35


RightShoulder.DesiredAngle = -3.14
	LeftShoulder.DesiredAngle = 0
	RightHip.DesiredAngle = 1.57
	LeftHip.DesiredAngle = 0
	wait(0)
end
	for i=1, 14 do

RightShoulder.MaxVelocity = 0.35
LeftShoulder.MaxVelocity = 0.35

RightShoulder.DesiredAngle = 0
	LeftShoulder.DesiredAngle = -3.14
	RightHip.DesiredAngle = 0
	LeftHip.DesiredAngle = 1.57

wait(0) end


RightShoulder.MaxVelocity = 0.15
LeftShoulder.MaxVelocity = 0.15
end

script.Parent.Sound:Stop()

end

function go(mouse)

mouse.Button1Down:connect(function() dance() end)

end

script.Parent.Selected:connect(go)

I think you need to be on R6 for this to work
