Scripted a premium only cape. Non-premium user can still use it. Any fixes?

I coded a cape script. I'm not that familiar with premium only scripting, but I tried making this cape premium only in the first lines. This didn't exactly work. Non premium users also have access to the cape. Any fixes?

-- this is my revised cape script
-- I put it in a local script in StarteGui

local renderCap = 200 -- Stop rendering capes for players over 200 studs away
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local runServ = game:GetService("RunService")

if player.MembershipType ~= Enum.MembershipType.Premium then
    function canUseCape(player)
        return false
    end
end

    function canUseCape(player) --
        return true
