Learning about FE, but there is a problem with my GUI tweening Help?

I am fairly new to FE, I took a long break; (before all of the experimental stuff); and i came back to being forced to learn FE. So can someone please tell mem why this isn't working? I'm fairly certain i did the tweening correctly. (The print 'hi' was to test if it was actually reading the tween)

script.Parent.MouseButton1Click:Connect(function()
	game.ReplicatedStorage.ChangeTeamFinding:FireServer()
	script.Parent.Parent:TweenPosition(UDim2.new(0.351, 0,0.338, 0))
	print 'hi'
end)

NEVERMIND EVERYONE, FALSE ALARM. I was just being stupid, and pasted in the beginning tween info instead of the end tween info ;-;
