Why doesn't the Text UI not update?

When I press the right button text only updates the text in the properties but not in the UI.

Here's the script:

local LeftButton = Parent.Menu.Frame2.LeftArrowFace
local RightButton = Parent.Menu.Frame2.RightArrowFace

local Value = 0
local ListGuyDude = {"Face 1","Face 2","Face 3","Face 4","Face 5","Face 6","Face 7","Face 8"}

RightButton.MouseButton1Click:Connect(function()
	local FaceNumbers = game.StarterGui.Menu.Frame2.Face1
	Value = Value + 1

	if Value == 1 then
		FaceNumbers.Text = ListGuyDude[1]
	elseif Value == 2 then
		FaceNumbers.Text = ListGuyDude[2]
	elseif Value == 3 then
		FaceNumbers.Text = ListGuyDude[3]
	elseif Value == 4 then
		FaceNumbers.Text = ListGuyDude[4]
	elseif Value == 5 then
		FaceNumbers.Text = ListGuyDude[5]
	elseif Value == 6 then
		FaceNumbers.Text = ListGuyDude[6]
	elseif Value == 7 then
		FaceNumbers.Text = ListGuyDude[7]
	elseif Value == 8 then
		FaceNumbers.Text = ListGuyDude[8]
	elseif Value > 8 then
		Value = 1
		FaceNumbers.Text = ListGuyDude[1]

	end
end)
