{
    new Count;
    new str[45];
    new playername[MAX_PLAYER_NAME];
    SendClientMessage(playerid, -1, "Vip online:");
    for(new i = 0; i < MAX_PLAYERS; i ++)
    {
        if(Pinfo[i][VipLevel] >= 1)
        {
            Count ++;
            GetPlayerName(i, playername, sizeof(playername));
            format(str, sizeof(str), "%s %s",playername,VipName(i));
            SendClientMessage(playerid, -1, str);
        }
    }
    if(Count < 1) SendClientMessage(playerid, -1, "No Vip Online!");
