Hello, i've been working on a trucking job. I've got some problems with the way it works, i wanted it so when you get in a trucker and press 2 it shows "Attach the trailer", it does that, but when i attach the trailer, it doesn't do anything, can't seem to find where i've gone wrong here. could you take a look at tell me where i've gone wrong please.
