I been using Sandra's Truckingmissions script and edited a little so now its more like a "drug-delivery-before-time-runs-out" script. And I can set the time, but when a player is doing one of the missions, there is no timer shown, so the player cant see how much time he has left to reach the checkpoint and complete the mission.
Is it possible to set a timer into this script? http://pastebin.com/H4St1Q8x
