Script gives outfit in Studio, not in game?

Hey guys!

I have this script here where if you click on the GUI, it gives you the outfit. It works fine in Studio test mode, but not in-game. Does anyone see an error with my code?

script.Parent.MouseButton1Down:connect(function()
playername = script.Parent.Parent.Parent.Parent.Name
playerteam = script.Parent.Parent.Parent.Parent
player = Workspace:FindFirstChild(""..playername.."")
if player ~= nil then
	player:FindFirstChild("Shirt").ShirtTemplate = "http://www.roblox.com/asset/?id=267460168"
	player:FindFirstChild("Pants").PantsTemplate = "http://www.roblox.com/asset/?id=267460509"
end
end)

Thanks in advanced,

Michael
