How to remove thi GUI error?

Hello everyone

I'm trying to call my GUI code from matlab's main script where I'm setting there buttons' values there

but I keep receiving so many errors and each time I correct one another one pops out

My GUI script name is Compare.m and the figure's name is Compare.fig

Please help me correct the errors

Here's the name script's code:

    h = Compare; 
    guidata(h,handles);
    set(handles.pushbutton1_ButtonDownFcn, 'Value', a)
    set(handles.pushbutton2_ButtonDownFcn, 'Value', '002.png')
    set(handles.pushbutton3_ButtonDownFcn, 'Value', '003.png')
    set(handles.pushbutton4_ButtonDownFcn, 'Value', '004.png')
    set(handles.pushbutton5_ButtonDownFcn, 'Value', '005.png')
    callback = get(handles.pushbutton6_ButtonDownFcn, 'Callback');
    callback = strrep(callback, 'gcbo', 'handles.figure1');
    eval(callback);

The errors I get here are either :

• Reference to non-existent field 'pushbutton1_ButtonDownFcn'.
• Undefined function or variable 'handles'.

My GUI code is:

    function varargout = Compare(varargin)
    gui_Singleton = 1;
    gui_State = struct('gui_Name',       mfilename, ...
                       'gui_Singleton',  gui_Singleton, ...
                       'gui_OpeningFcn', @Compare_OpeningFcn, ...
                       'gui_OutputFcn',  @Compare_OutputFcn, ...
                       'gui_LayoutFcn',  [] , ...
                       'gui_Callback',   []);
    if nargin && ischar(varargin{1})
        gui_State.gui_Callback = str2func(varargin{1});
    end

    if nargout
        [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
    else
        gui_mainfcn(gui_State, varargin{:});
    end
    function Compare_OpeningFcn(hObject, eventdata, handles, varargin)
    handles.output = hObject;
    guidata(hObject, handles);

    Imageg3 = rgb2gray(Imaged3); 
    Imageg4 = rgb2gray(Imaged4); 
    Imageg5 = rgb2gray(Imaged5);

    axes(handles.axes6);
    imshow(I5);

Please Help me

Thank You

For your second line, instead of

guidata(h,handles);

use

handles = guidata(h);
