pawn Code:

CMD:admins(playerid, params[])
{
            new string[128];
            new count = 0;
            SendClientMessage(playerid, COLOR_PURPLE, "|____________________Admins Online____________________|");
            {
              if(IsPlayerAdmin(playerid))
              {

                        format(string, sizeof(string), "Administrator: %s ",adminid(admin)); // replace it with your admin variable
                        SendClientMessage(playerid, -1, string);
                        count++;
               }
            }
                        return 1;
}

They needs to be spoon-feeded.
And please whenever you copy-paste code from your scripts, atleast try to change your variable to their adjustments.
