I have 06 popup menu and I want to get its values ​​to calculate DATE_START and DATE_END

hi everyone, I have 06 popup menu in GUI and I want to get its values ​​to calculate

date_start = [da,dm,dj];

date_end = [fa,fm,fj];

to use them in a push button

here is the script of each push button sata all

% --- Executes on selection change in d_annee.
function d_annee_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popda=contents(get(hObject,'Value'));
da=num2str(cell2mat(popda));
% --- Executes on selection change in d_mois.
function d_mois_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popdm=contents(get(hObject,'Value'));
popdm;
if(strcmp(popdm,'Janvier'));
    dm='01'
elseif(strcmp(popdm,'Février'));
    dm='02'
    elseif(strcmp(popdm,'Mars'));
    dm='03'
    elseif(strcmp(popdm,'Avril'));
    dm='04'
    elseif(strcmp(popdm,'Mai'));

    dm='10'
    elseif(strcmp(popdm,'Novembre'));
    dm='11'
    elseif(strcmp(popdm,'Décembre'));
    dm='12'
end
% --- Executes on selection change in d_jour.
function d_jour_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popdj=contents(get(hObject,'Value'));
dj=num2str(cell2mat(popdj));
% --- Executes on selection change in f_annee.
function f_annee_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popfa=contents(get(hObject,'Value'));
fa=num2str(cell2mat(popfa))
% --- Executes on selection change in f_mois.
function f_mois_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popfm=contents(get(hObject,'Value'));
popfm;
if(strcmp(popfm,'Janvier'));
    fm='01'
elseif(strcmp(popfm,'Février'));

    elseif(strcmp(popfm,'Novembre'));
    fm='11'
    elseif(strcmp(popfm,'Décembre'));
    fm='12'
end
% --- Executes on selection change in f_jour.
function f_jour_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popfj=contents(get(hObject,'Value'));
fj=num2str(cell2mat(popfj));

% --- Executes on button press in stat_all.
function stat_all_Callback(hObject, eventdata, handles)
% hObject    handle to stat_all (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

global dj dm da fj fm fa 
handles=guidata(gcbf);
date_start=[da,dm,dj];
date_end=[fa,fm,fj];

Mustapha - if you are going to use GUIDE to build your GUI, then rather than using global variables to share information between callbacks, use the handles structure to save the dm or fm data and then access this data from another callback. For example, in your d_mois_Callback callback, do

function d_mois_Callback(hObject, eventdata, handles)
contents=cellstr(get(hObject,'String'));
popdm=contents(get(hObject,'Value'));
popdm;
if(strcmp(popdm,'Janvier'));
    dm='01';
elseif ...
end
handles.dm = dm;
guidata(hObject, handles); % this saves the updated handles structure

Then in your pushbutton callback you would do

function stat_all_Callback(hObject, eventdata, handles)
dm = handles.dm;
fm = ...; % etc.
end

Note that you may want to check for the existence of these fields (dm, fm, etc.) before you try to access them. Or assign default values to these fields in the OpeningFcn of your GUI. Also, you have duplicate code in your two popup menu callbacks. Since you know

contents=cellstr(get(hObject,'String'));
popfm=contents(get(hObject,'Value'));

then perhaps you could just find popfm in contents and use its index as your dm or fm value (assuming that your list of months are in the usual order).

merci beaucoup , ça marche trés bien .
