}
}

new string[50];
SendClientMessage(playerid, COLOR_TEAL, "Current Online Admins:");
for(new i = 0; i <MAX_PLAYERS; i++) {

format(string, sizeof(string), "%s (%d)", ReturnPlayerName(i), i);

}
}
}
else {
SendClientMessage(playerid,0xFF0000AA, "There Are Currently No Admins Online.");
}
return 1;
}


and then put this function at the bottom :

stock ReturnPlayerName(playerid)
{
new PlayerName[MAX_PLAYER_NAME];
GetPlayerName(playerid,PlayerName,sizeof(PlayerName));
return PlayerName;
}



Edit: remember to replace the "ADMIN" and Level[playerid] with what you use to check if the player is admin.
