Try adding a space:

pawn Код:

if(indm[playerid] == 2 && indm[killerid] == 2)
    {
        SetPlayerScore(killerid,GetPlayerScore(killerid) - 1);
        SendClientMessage(killerid,red,"Dont kill your own men!");
        SetPlayerHealth(killerid,0);
    }

// edit blackwabe might be right too.. try using the else situation, IDK if it will now work:

pawn Код:

if(indm[playerid] == 2 && indm[killerid] == 2)
    {
        SetPlayerScore(killerid,GetPlayerScore(killerid)-1);
        SendClientMessage(killerid,red,"Dont kill your own men!");
        SetPlayerHealth(killerid,0);
        return 1; //shouldnt it be here?
    }
    else
    {
       SendClientMessage(killerid,red,"Dont kill outside a DM!");
       return 1;
    }

remove the message if youd like. IDK if it will work im still a newb.
