why this GUI error occurs?

I made a simple GUI function, but there are a tiny problem. GUI works, but in command window,
*'F1_CreateFcn'은(는) 정의되지 않은 함수 또는 변수입니다.
오류 발생: gui_mainfcn (line 95) feval(varargin{:});
오류 발생: untitled2 (line 42) gui_mainfcn(gui_State, varargin{:});
오류 발생: matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)untitled2('F1_CreateFcn',hObject,eventdata,guidata(hObject))*
I saw this error...
source code like this.
function varargout = untitled2(varargin)
% UNTITLED2 MATLAB code for untitled2.fig
% UNTITLED2, by itself, creates a new UNTITLED2 or raises the existing
% singleton*.
%
% H = UNTITLED2 returns the handle to a new UNTITLED2 or the handle to
% the existing singleton*.
%
% UNTITLED2('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED2.M with the given input arguments.
%
% UNTITLED2('Property','Value',...) creates a new UNTITLED2 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled2_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled2_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

I want to know why this error occurs and how can I solve this... My advisor can MATLAB, but he is sooooooo busy so I cannot ask him...

It probably has something to do with the fact that your code has a y_CreateFcn but nothing else having to do with y_*, as if you editted the F1 to y at some point.

Add a new function:
function F1_CreateFcn(hObject, eventdata, handles)
% hObject handle to F1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles empty - handles not created until after all CreateFcns called
% Hint: edit controls usually have a white background on Windows.
% See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end
