Help with orientation

Hi,

I need help with this script

local TweenSerivice = game:GetService("TweenService")

local Properties = {

Position = Vector3.new(3, 25.5, 0)

orientation = Vector3.new(-20, 0, 90)

}

local TweenInformation = TweenInfo.new(4.5,Enum.EasingStyle.Sine,Enum.EasingDirection.Out)

local Tween = TweenSerivice:Create(script.Parent,TweenInformation,Properties)

wait(10)

Tween:Play()

theres an issue on line 4. Im not sure how to do orientation yet. Is there any one who knows a bit about this?

Thanks,
