You might need to use
Dx = str2num(Dx)
before calling the function is it possible?

Well the use of hObject is for a particular callback, i.e. the one currently executing. If you want to access the content of other elements (pushbuttons, popup menus, etc) you need to use their handles.
In your example, when pressing the pushbutton you want to call:
itemsx = get(handles.textbox1,'String');
index_selectedx = get(handles.textbox1,'Value');
Dx = itemsx{index_selectedx};
which is more likely to work. In my example "handles.textbox1" is the handles generated by GUIDE (assuming you used GUIDE) that you can change to anything you want. It it does not work please show the error message so we can help you better.
