        if (PlayerOrg[i] == PlayerOrg[playerid] && i != playerid)
        {
            format(string,sizeof(string),"%s", PlayerName(i));
            strcat(MyDialog, string);
        }

    ShowPlayerDialog(playerid,99000,DIALOG_STYLE_LIST,"Memberlist",MyDialog,"Ok","Alright");
 }

Try this, and do the same for the "case 0" which is also wrong.
