I have a problem with reading a popup menu string and using it in a switch-case function in another button. My popup menu shouldn't have any function but indicating the value. But the button should know the value of popup menu and switch the case according to it. Thanks in advance.

My code:

 function pushbutton1_Callback(hObject, eventdata, handles)
 switch popupmenu4value
    case 'A'
%function of A
    case 'B'
%function of B
 function popupmenu4_Callback(hObject, eventdata, handles)
 contents = get(handles.popupmenu4,'String'); 
 popupmenu4value = contents{get(handles.popupmenu4,'Value')};

Mark as "Accepted" then, so people like me don't have to waste time and come in and read all the way to the bottom only to discover it's been solved already.
