[SOLVED] Is it possible to compare GUI sizes with each other?

Is there a way to get this script to work?

local r = Random.new()
local Bar = script.Parent.Bar
local Store = script.Parent.Parent.SizeValue
while true do wait(14)
	Store.Size = Bar.Size
	wait(1)
	Bar.Size = UDim2.new(r:NextNumber(0,0),r:NextNumber(0,613),r:NextNumber(0,0),r:NextNumber(34,34))
--Past here is where I am asking.
	if Bar.Size < Store.Size then
		Bar.BackgroundColor3 = Color3.new(0.298039, 1, 0)
	else if Bar.Size > Store.Size then
			Bar.BackgroundColor3 = Color3.new(1, 0, 0)
		end
	end
end
