>?Player Point Script Help?

Well , I want To Add a New Feature To my game , Do Basically , I have This "Raining PP Script"

--[[
    ScriptGuider's Player Points Rain v.2, edited by stopthecakehate and kiddodew

    This script will spawn random coins across a chosen area. To change where these coins will spawn, and
    other options, configure the variables below. Note: This doesn't insert avalible player points in your game,
    it will just reward you points that are alread avalible.

-------------------------------
 -------|Configurable|--------
-------------------------------
local height = 120                       -- How many studs high the rain starts at

local CoinSize = Vector3.new(4, 0.2 ,4);  -- size of the coin

local RainDelay = 0.1                    -- how long between each coin will spawn. 
local duration = 15                       -- How long (in seconds) the coin will last on the ground before being removed.

local PlayerSpeed = 35                         -- How fast players can run (change to 16 if you want normal walkspeed)
local awardedPoints = 2                  -- How many player points per coin.

local target = Workspace:FindFirstChild( "BasePlateLayer2" )  --[[ Here, put the NAME of the BRICK you want the points to rain over.

    Say for example you want the points to rain over a part called "Base". Then it should look like:

    local target = Workspace:WaitForChild( "Base" )

There We Go , It is not Mine ... Free Model but , Is there away to ONLY make It Active When A Person In my Game Buys A Shirt Called Activation For Rain Script And Then it start
