Matlab GUI set error

Hi,
I keep getting this error and I don't know why. Or I know what is causing it but don't know how to resolve it. I need to load a .mat file which has a variable within called sMap. But if I load this file, the handles.box causes an error with the following remark.
Reference to non-existent field 'box'.
How can I load this mat file and still have access to the box.

The code is as follows:
% --- Executes just before UnsupervisedRecognitionEngine is made visible.
function UnsupervisedRecognitionEngine_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% varargin command line arguments to UnsupervisedRecognitionEngine (see VARARGIN)
% Choose default command line output for UnsupervisedRecognitionEngine
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
% UIWAIT makes UnsupervisedRecognitionEngine wait for user response (see UIRESUME)
% uiwait(handles.figure1);
% --- Outputs from this function are returned to the command line.
function varargout = UnsupervisedRecognitionEngine_OutputFcn(hObject, eventdata, handles)
% varargout cell array for returning output args (see VARARGOUT);
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Get default command line output from handles structure
varargout{1} = handles.output;
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
B = xlsread('animals_data_newanimal.xlsx');
sDataStr_rec = som_data_struct(B);
sDataStr_rec=som_normalize_data(sDataStr_rec,'som_var_norm');
load('e:\matlab\ute01\animals.mat');
rec_bmu = som_bmus(sMap, sDataStr_rec);
n = strcat('The Best Matched Neuron is: ', num2str(rec_bmu));
set(handles.box,'string', n);
function box_Callback(hObject, eventdata, handles)
% hObject handle to box (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: get(hObject,'String') returns contents of box as text
% str2double(get(hObject,'String')) returns contents of box as a double
% --- Executes during object creation, after setting all properties.
function box_CreateFcn(hObject, eventdata, handles)
% hObject handle to box (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');

This link will help you solve this problem: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/. Basically set a breakpoint at the line it gives you an error at, examine the handles structure, and see that box is not a member of handles. My guess are that the load() statement loads a handles that blows away your existing handles, or that you have a "clear" or something similar in there somewhere.
