Well if you payed attention to my little tutorial three posts up... you'll see you need three floats, getplayerpos, a loop to check for players, isplayerinrangeofpoint, and finally sendclientmessagetoall sends the message to EVERYONE therefore you need to use sendclientmessage in order to send the message to certain players.

PM me if you have skype and I'll be will to support you there.
