if statement not working properly?

I have this script that is supposed to make the player's gui visible if playing is equal to false and make it not visible if playing is equal to true but for some reason the script constantly outputs saying "playing = false" even when I make the playing value equal true? The playing value is a boolean value in a folder in the workspace

while wait() do
	if game.Workspace.Values.Playing.Value == false then
		print("playing = false")
		script.Parent.Visible = true
	else if game.Workspace.Values.Playing.Value == true then
				print("playing = true")
			script.Parent.Visible = false
		end
	end
end

Please help!
