Matlab - GUI Listbox

Hola a todos y gracias de antemano.

Estoy haciendo una GUI en Matlab y quiero que seleccionar un valor en una listbox y que ese valor se exporte a un archivo excel cuando pase a la siguiente "pantalla".

Lo había hecho así, pero no me funciona:

function RFuente1_Callback(hObject, eventdata, handles)
% hObject handle to RFuente1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
index_selected = get(hObject,'Value');
index_selected_texto=get(hObject, 'String');
handles.RFuente1=index_selected_texto;
guidata(hObject, handles);

function Siguiente_Callback(hObject, eventdata, handles)
% hObject handle to Siguiente (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

RFuente1= handles.RFuente1;

A={'Fuente';RFuente1};
xlswrite('situacion.csv',A,'B1:B2');

clear,clc,close all

D16;


Muchas gracias a todos,

haber sube tu guide para verlo.

Hola a todos,

Al final lo he hecho de otra manera porque lo que quería hacer en realidad es muy sencillo y no tenía por qué complicarme tanto.

function varargout = fuentes(varargin)
% FUENTES M-file for fuentes.fig
% FUENTES, by itself, creates a new FUENTES or raises the existing
% singleton*.
%
% H = FUENTES returns the handle to a new FUENTES or the handle to
% the existing singleton*.
%
% FUENTES('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in FUENTES.M with the given input arguments.
%
% FUENTES('Property','Value',...) creates a new FUENTES or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before fuentes_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to fuentes_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help fuentes

Saludos

me refiero los archivos *.fig y el archivo *. Ese debe subir

Que es fuente2?. Que es fuente1?
