how to use the pop up menu in gui which contains "Yes" and "No", then linked to pushbutton

function pushbutton_Callback(hObject, eventdata, handles)

% hObject handle to lanjut (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

a=readfis('coba2');

out=evalfis([handles.G01 handles.G02 handles.G03 handles.G04 handles.G05 handles.G06 handles.G07 handles.G08

handles.G09 handles.G10 handles.G11 handles.G12 handles.G13 handles.G14 handles.G15 handles.G16, a]);

set(handles.hasil,'string',out);

% --- Executes on selection change in popupmenuG01.

function popupmenu_Callback(hObject, eventdata, handles)

% hObject handle to popupmenu (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

contents = get(handles.popupmenu,'String');

popupmenuvalue = contents{get(handles.popupmenu,'Value')};

guidata(hObject, popupmenuvalue);

% Hints: contents = cellstr(get(hObject,'String')) returns popupmenuG01 contents as cell array

% contents{get(hObject,'Value')} returns selected item from popupmenuG01

% --- Executes during object creation, after setting all properties.

function popupmenuG01_CreateFcn(hObject, eventdata, handles)

% hObject handle to popupmenuG01 (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles empty - handles not created until after all CreateFcns called

% Hint: popupmenu controls usually have a white background on Windows.

% See ISPC and COMPUTER.

if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))

set(hObject,'BackgroundColor','white');

end

yes this is a bit of my program code, but when I run there is an error like this

Attempt to reference field of non-structure array.
