function pushbutton1_Callback(hObject, eventdata, handles)
u=get(handles.popupmenu1,'Value');
v=get(handles.popupmenu1,'Value');
if u == 1 && v ==1
x_String = get(handles.edit1,'String');
x_numeric = str2num(x_String);
result = x_numeric*2;
result_String = num2str(result_numeric);
set(handles.text1,'String',result_String);
result_String = num2str(result_numeric);
set(handles.text1,'String',result_String);

Other than duplicating the last two lines, what doesn't work about it? Do you have an error message? Or it just doesn't do what you want?

Wild solution guess:
Do not start the GUI by double-clicking the .fig file. Instead, start the GUI by running the .m file.
