Why won't this scrolling frame scroll on KeyDown?

I am making something for a game, and for some reason, the script returns with no errors, but it does nothing. I have tried scrolling it all the way, finding the position, and scrolling it back. Nothing will work for me. It is supposed to be when you hit a button, it will scroll a 4th of the way in either direction, and change the tool value.

I have pictures here of what it looks like: In game: http://imgur.com/vWce8yc,8CUxw25 In the explorer: http://imgur.com/vWce8yc,8CUxw25#1

Here is the code:

game.StarterGui:SetCoreGuiEnabled(4, false)
Player = game.Players.LocalPlayer
Mouse = Player:GetMouse()

Size = script.Parent.AbsoluteWindowSize
Rsize = Size/4

Mouse.KeyDown:connect(function(key)
	if key == "e" then
		for Scroll = 1,5 do
		script.Parent.CanvasPosition = script.Parent.CanvasPosition +Vector2.new(Rsize, 0)
		end
		if script.Parent.SelectedTool.Value ~= 4 then
			script.Parent.SelectedTool.Value =  script.Parent.SelectedTool.Value +1
		end
	end
end)
Mouse.KeyDown:connect(function(key)
	if key == "q" then
		for Scroll = 1,5 do
		script.Parent.CanvasPosition = script.Parent.CanvasPosition -Vector2.new(Rsize, 0)
		end 
		if script.Parent.SelectedTool.Value ~= 1 then
			script.Parent.SelectedTool.Value =  script.Parent.SelectedTool.Value -1
		end
	end
end)

I just basically copied this from the Roblox wiki lesson. Here's the code to this or link

-- In a LocalScript in StarterGui:
 
-- Create ScreenGui
local screenGui = Instance.new("ScreenGui")
screenGui.Parent = script.Parent
