How is it not shown? I re-looked the code in case I missed anything but the code is fine.

As for the toggling, an array to store whether the player is in duty or not is needed.

PHP код:

// global:
new gPlayer_OnDuty[MAX_PLAYERS];
// OnPlayerConnect:
gPlayer_Duty[playerid] = 0;
// unless you want the player to be automatically on duty or even after logging, set them to 1 where needed
CMD:aod(pid, params[]) 
{ 
    if(!IsPlayerAdmin(pid)) return SCM(pid, COLOR_RED, ADMIN_MESSAGE); 
   
    new string[65], name[MAX_PLAYER_NAME]; 
    GetPlayerName(pid, name, MAX_PLAYER_NAME);
  
    if (!gPlayer_Duty[playerid]) // not on duty
    {
        SPH(pid, 400); 
        SetPlayerArmour(pid, 100); 
   
        format(string, sizeof string, "Admin %s is now on duty. /w him for help.", name); 
        SCMToAll(COLOR_LIME, string); 
      
        gPlayer_Duty[playerid] = 1; // set them on duty
    }
    else // on duty
    {
          // code for health/armour..
      
        format(string, sizeof string, "Admin %s is no longer on duty.", name); 
        SCMToAll(COLOR_LIME, string); 
      
        gPlayer_Duty[playerid] = 0;
    }
    return 1; 
}
