[Scenario]

Why do some people think they're problems are so much more important than everybody else?

pawn Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
        new string[128];
        format(string, sizeof(string), "You are entering vehicle %i",vehicleid);
        {
        if(GetVehicleModel(GetPlayerVehicleID(playerid) == 487 && team[playerid] != 6);
        RemovePlayerFromVehicle(playerid); //Indent
        SendClientMessage(playerid, YELLOW, "Restricted to S.T.A.R.S. !!");
        }
        return 1;
}

Why don't you go back and look at the particular line you're having trouble with, then compare it with what I have above. You'll see how idiotic your mistake was.
