How to reset the pop-up menu value in GUI?

Hi,
This is my pop-up coding.
function Domain_Callback(hObject, eventdata, handles)
contents = cellstr(get(hObject,'string'));
popchoice = contents{get(hObject,'value')};
if (strcmp(popchoice, 'Time Domain'))
Domain_value = 2;
elseif (strcmp(popchoice, 'Frequency Domain'))
Domain_value = 3;
elseif (strcmp(popchoice, '----'))
Domain_value = 1;
end
assignin('base', 'Domain_value', Domain_value);
And this is my reset button function
function Clear_button_Callback(hObject, eventdata, handles)
set(handles.Domain,'Value',1);
It partly works. In GUI if I press the reset button, the pop-up menu will show '----', but the value won't change.
So how can I reset the pop-up value to 1?

Jomei - but you do understand why the value is not being set in the workspace, correct? And do you really need it to be defined in the workspace? If so, why?

If you need something in your base workspace to be updated when you change things in your GUI, you could consider a programmatic class-based GUI. The example in the how to create a GUI thread should be relatively easy to adapt to your needs.
This different design would also remove the need for assignin.
