Roblox' Animation works fine offline, but not online. Local Scripts used. How can this be fixed?

Here is a simple excerpt from a Local Script in the starter pack.

function KeyPress(PressedKey)
local key = string.lower(PressedKey)
	--if key:byte() == 9 then ----------------------------PARRY ANIMATION/CODE
		if key == "r" then		
		local hum = script.Parent.Parent.Character:FindFirstChild("Humanoid")
		local occ = script.Parent.Parent.Character:findFirstChild("Torso"):findFirstChild("isOccupied")
		if occ.Value == false then
			occ.Value = true
			
		local anim = Instance.new("Animation")
		--anim.AnimationId ="http://www.roblox.com/Asset?ID=27762691"
		anim.AnimationId = "http://www.roblox.com/asset/?id=27762691"
		local anime = hum:LoadAnimation(anim)
		anime:Play()
		wait(2)		
		anime:Stop()
		anime:remove()
		wait(.3)
		occ.Value = false
		end
	end
