List command bug,error /list skript

[AkroDogy2005]

Hey i have this skript:

command /list:
    aliases: /who
    trigger:
        if player is op:
            message "&7>&8&l&m--------------------------------------&7<"
            message ""
            set {_amountplayers} to amount of players
            message "&8&7(&e!&7) &fOnline players: &e%{_amountplayers}%&f/&e200"
            loop all players:
                if loop-player has permission "akrolist.staff":
                    add loop-player to {_online staff::*}
                    message "&8&7(&e!&7) &fStaff: &e%{_online staff::*}%"
                if loop-player has permission "akrolist.donor":
                    add loop-player to {_online donor::*}
                    message "&8&7(&e!&7) &fDonors: &e%{_online donor::*}%"
            message ""
            message "&7>&8&l&m--------------------------------------&7<"

All it's good with 1 player (Proof» http://prntscr.com/m1vn1i)
But with 2 player i have this bug (Proof» http://prntscr.com/m1vn6x)

1. If isn't staff/donors online, in console it's disapear Staff and Donor lines, how can i resolve this? ( Proof» http://prntscr.com/m1vnr7)
2. How can i make a command which to make more lines: ex: I want donor line, staff line, and noob line without to open the skript file and edit.
Online players: 0
Staff: 0
Donors: 0
Noobs: AkroDogy (if the player has permission using a command to set it ex:akrolist.noob ingame: /setpermision noobs akrolist.noob)
3. If isn't staff/donors online, how can i do in /list command to be Staff: 0,Donor: 0?

You should message after the loop

No im not going to spoonfeed you. just move the message "online donor stuff" to somewhere after the loop
