Suppose we select a value from the menu and we have to pass that to another push button how should we do it? I've tried using it like this in the popupmenu function but they are giving me wrong values on execution .
function popupmenu1_Callback(hObject, eventdata, handles)
% hObject handle to popupmenu1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: contents = cellstr(get(hObject,'String')) returns popupmenu1 contents as cell array
% contents{get(hObject,'Value')} returns selected item from popupmenu1
global salval;
switch get(handles.popupmenu1,'Value')
case 1
salval=xlsread('salval1.xlsx','sheet1');
case 2
salval=xlsread('salval2.xlsx','sheet1');
case 3
salval=xlsread('salval3.xlsx','sheet1');
case 4
salval=xlsread('salval4.xlsx','sheet1');
case 5
salval=xlsread('salval5.xlsx','sheet1');
otherwise
end
%set(handles.popupmenu1, 'UserData', myString);
%handles.salval=salval;
set(handles.popupmenu1, 'UserData');
guidata(hObject,handles);
end
and used the value in pushbutton like this: function matchval_Callback(hObject, eventdata, handles)
S = get(handles.popupmenu1, 'UserData');
I don't know if i'm right .Can anybody please help.
Thank you Deepa

What is the aim of this?
set(handles.popupmenu1, 'UserData')
Maybe you want
set(handles.popupmenu1, 'UserData',Value)
You can also use guidata like this:
handles.Value=Value
guidata(hObject,handles);
In another function, call it:
Value=handles.Value

Is there a correct answer more clearly stated for this question? I am at the same point in my GUI. I can import data, populate the popups, retain the popup value or index, now I want to spit a structure and those indexes back to a pushbutton calling a function that will give me my end results. Any direction or applicable links would be appreciated.
Thanks.
