How can I get a Script to completely start over?

I have made a FPS limiter script, and it's working just fine. But if the user changes the FPS limit to something else, they would need to rejoin the game for the changes to take effect, because the script wouldn't register the changes.

I have tried disabling and enabling again and cloning but none worked. Can someone help me out?

Script: (without the resetting code)

local FPSCAP = game.StarterGui.ScreenGui.System.FPS.LimitFPSto.Value 
local LOOPCount = 200 
local MLoopCount = 27 

local FPS = 0
local Broken = 0
local function DOLOOP()
    spawn(function()
        while true do
            game:GetService("RunService").Heartbeat:Wait()
            if FPS+5 < FPSCAP and Broken <= LOOPCount*MLoopCount then
                Broken += 1
                break
            end
        end
    end)
end

game:GetService("RunService").RenderStepped:Connect(function(delta)
    FPS = 1/delta
end)

spawn(function()
    while true do
        game:GetService("RunService").Heartbeat:Wait()
        if FPS >= FPSCAP then
            spawn(function()
                for i = 1, LOOPCount do
                    DOLOOP()
                end
            end)
        end
    end
end)
spawn(function()
    while wait(1) do
        Broken = 0
    end
end)
