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{:});
