Why is this script not changing my clickSpeed?

Hi, I've been working on a script to change click speed depending on how much money you have, but it hasn't been working.

local gui = script.Parent
local frame = script.Parent.Frame
local mainButton = frame.mainButton
local Player = game:GetService("Players").LocalPlayer
local canOof = true
local doubleSpeed = 7955426
local mpService = game:GetService("MarketplaceService")
local oofs = game.Players.LocalPlayer:WaitForChild("leaderstats"):WaitForChild("Oofs")
local clickSpeed = script.Parent.clickSpeed
local rangeOne = NumberRange.new(100,299)
local rangeTwo = NumberRange.new(300,599)


local function Setup(player)
	print("This script exists!")
	if oofs <= 99 then
		clickSpeed.Value = 1
		print(clickSpeed)
	elseif oofs >= rangeOne.Min and oofs <= rangeOne.Max then
		clickSpeed.Value = 0.9
		print(clickSpeed)
	elseif oofs >= rangeTwo.Min and oofs <=rangeTwo.Max then
		clickSpeed.Value = 0.8
		print(clickSpeed)
	end
end

local playersInGame = game.Players:GetPlayers()
for i = 1, #playersInGame do
	Setup(playersInGame[i])
end

Thanks.
