 function listbox1 _Callback(hObject, eventdata, handles)
 index_selected = get(hObject,'Value');
 list = get(hObject,'String');
 item_selected = list{index_selected}; % Convert from cell array % to strin
 disp(item_selected);

function listbox2 _Callback(hObject, eventdata, handles)

index_selected = get(hObject,'Value');

list = get(hObject,'String');

item_selected2 = list{index_selected};

disp(item_selected2);

function OK_PUSHBUTTON _Callback(hObject, eventdata, handles)

function itemFromColumnC = GetColumnC(handles, textdata);

itemFromColumnC = []; % Initialize to null

% Get the item number that they selected.

selected1 = get(handles.item_selected1, 'value');

selected2 = get(handles.item_selected2, 'value');

% Get the contents items1 = get(handles.item_selected2, 'String');

items2 = get(handles.item_selected2, 'String'); % Get the selected item

selectedItem1 = items1{selected1};

selectedItem2 = items2{selected2};

% Now compare

if selected1 == selected2

itemFromColumnC = textdata{selected1, 3};

end message = sprintf('%s',itemFromColumnC);

uiwait(msgbox(message));

 For Example:
 Listbox1 input=" PAss"
 Listbox2 input=" Fail"
 Grade Output =" D Grade"

(See the 7th row in xls sheet)

@Jan Simon :

I Have 2 listboxes and one pushbutton in my gui.

If I select inputs from listbox and OK Button is clicked then it has to compare with the excel sheet values. Once it got the match of 2 inputs then it has to display the corresponding 3rd column value.

If I select Pass and Fail from listbox1 and listbox2 respectively...then it has to display the corresponding 3rd column value i.e, D Grade

I think you want to use strcmpi() instead of ==

if strcmpi(selectedItem1, selectedItem2)
  % They match
else
  % they don't match
end
