GUI: Having trouble displaying data in table

So I have this pushbutton for loading data:

function loadfile_button_Callback(hObject, eventdata, handles)

feature_list = {'list', 'of', 'features'};

 
[Acontrol_data, Acontrol_labels, APD_data, APD_labels, compare_features, compare_activity] = check_data(handles.control_data, ...
handles.control_labels, handles.PD_data, handles.PD_labels, feature_list);

handles.Acontrol_data = Acontrol_data;
handles.Acontrol_labels = Acontrol_labels;
handles.APD_data = APD_data;
handles.APD_labels  = APD_labels;

if(any(compare_features) || any(compare_activity))
    
    handles.data_summmary = summarize_data(horzcat(Acontrol_data, APD_data));
    
    guidata(hObject, handles);
    set(handles.uitable1,'Data',handles.data_summary);
else
    f = warndlg('Control and PD classes include different features. Please check spelling capitalization, as well as the Feature Activity cells.'...
                ,'Error');
end

I'd like to set uitable1 to display the matrix "data_summary". I keep getting the error:

Reference to non-existent field 'data_summary'.

Error in HRV_GUI>loadfile_button_Callback (line 222)
    set(handles.uitable1,'Data',handles.data_summary);

Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error in HRV_GUI (line 38)
    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)HRV_GUI('loadfile_button_Callback',hObject,eventdata,guidata(hObject))

 
Error while evaluating uicontrol Callback

Any advice? Thanks!

    handles.data_summmary = summarize_data(horzcat(Acontrol_data, APD_data));

handles.data_summmary . Three 'm'.

ah, duh. Thanks
