MATLAB: Browse Button in GUIDE issue

guideuigetfile

Hi, I have a callback function for a Browse button (to select a file) in a GUIDE generated fig:
% --- Executes on button press in browse_pushbutton.
function browse_pushbutton_Callback(hObject, eventdata, handles)
% hObject    handle to browse_pushbutton (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
[FileName,PathName] = uigetfile({'*.dat;*.txt','Input Files (*.dat, *.txt)';'*.*','All Files (*.*)'},'Select a file for input');
if ~isequal(FileName,0)
    set(handles.path_text,'String',[PathName FileName]);
end
Issue I am having is after I select the file in the uigetfile window and click on open, I get the following error:
Attempt to reference field of non-structure array.
Error in compute_ENOB>browse_pushbutton_Callback (line 302)
    set(handles.path_text,'String',[PathName1 FileName1]);
Error in gui_mainfcn (line 96)
        feval(varargin{:});
Error in compute_ENOB (line 42)
    gui_mainfcn(gui_State, varargin{:});
Error in
@(hObject,eventdata)compute_ENOB('browse_pushbutton_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback
I am not sure what is wrong.

In your code, it says:
set(handles.path_text,'String',[PathName FileName])
In the error message, it says:
set(handles.path_text,'String',[PathName1 FileName1])
Wrong variable name?
