I didn't know where to put this so I've chosen the general section.
I'm trying to give penalties to drivers so I checked the Commands.txt and read:

Penalties :

/p_dt USERNAME :give drive through penalty
/p_sg USERNAME :give stop-go penalty
/p_30 USERNAME :give 30 second time penalty
/p_45 USERNAME :give 45 second time penalty
/p_clear USERNAME :clear a time or pit penalty

I typed the following:

/p_dt yisc[NL]

Hit enter and receive the message: Wrong parameter
Same goes for the other options for penalties.
What's am I doing wrong with this?

p.s: my LFS-username is without the capital Y so that isn't the problem.

Are you typing the commands on a server where you are logged in as an Administrator or at least have the necessary rights to perform these commands?

Then it would come up with 'you must have admin rights'.

I've just tried it and it works fine

Thanks guys. I typed those command as an admin but logged on to a server on my localhost. I've tried it on one of my dedicated servers and all is working fine. I guess those commands can't be executed on a localhost or it has some kind of bug. My problem is solved now.
