plotting from excel

I am unable to plot from Excel Sheet. My code is s follows. If someone can please help
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB

% handles    structure with handles and user data (see GUIDATA)

[file, path] = uigetfile('*.xls');
handles.fileName = fullfile(file, path);
guidata(hObject,handles);
% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
if isfield(handles, 'fileName')
    filename = get(handles.fileName);
    values = xlsread(filename);
    xCol = values(:,2);
    yCol = values(:,3);
    set(handles.axes1,'Visible','on');
    plot(handles.axes1,xCol,yCol)
end

Best Answer

handles.fileName = fullfile(file, path);
That creates fileName as a character vector field inside handles.
    filename = get(handles.fileName);
If handles.FileName were a handle, then that would return a structure of public properties of the handle.
However, handles.FileName is not a handle, just a character vector. You just need
    filename = handles.fileName;
