"the proximity prompt can be exploited via auto clicker and give 500 afcash. please fix"

To fix the exploit, we can add a cooldown to the proximity prompt trigger. This will prevent the player from triggering the prompt repeatedly in a short amount of time.

```lua
local sound = script.Parent.Parent.Parent.sound.Sound
local afcashValue = 100
local cooldown = 10 -- 10 seconds cooldown
local lastTriggered = {}

local function play(player)
    local currentTime = os.time()
    if lastTriggered[player.UserId] and currentTime - lastTriggered[player.UserId] < cooldown then
        return
    end

lastTriggered[player.UserId] = currentTime
    sound:Play()
    local leaderstats = player:FindFirstChild("leaderstats")
    if leaderstats then
        local afcash = leaderstats:FindFirstChild("AFCash")
        if afcash then
            afcash.Value = afcash.Value + afcashValue
        end
    end
end

script.Parent.Triggered:Connect(play)
```

In this script, we create a `lastTriggered` table to keep track of the last time each player triggered the prompt. When the prompt is triggered, we check if the player has triggered it within the cooldown period. If they have, we simply return and do nothing. If they haven't, we update their last triggered time and proceed as before.
