hi all

i've a query here on what i've done wrong and i'm not sure where exactly the problem is.

I build a gui and in the gui, there is a static text box and a pushbutton.

when i press a pushbutton, it should come up with a text where i'm using set function.

function pushbutton19_Gen_Bands_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton19_Gen_Bands (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

for z=1:20
%% Band 1
handles.thepath = 'C:\System\image files';
handles.jpegFiles = dir(fullfile(handles.thepath, '*.jpg'));
for k = 1:length(handles.jpegFiles)
if k==1
handles.filename=handles.jpegFiles(k).name;
data1 = imread([handles.thepath filesep handles.filename]);
data2=imcrop(data1,[1 1 1392 52]);
imwrite(data2,'band1.JPG');
set(handles.text5_monitor,'String','band 1 created');
else
break;
end

end

%% Band 2
handles.thepath = 'C:\System\image files';
handles.jpegFiles = dir(fullfile(handles.thepath, '*.jpg'));

for j = 1:length(handles.jpegFiles)
if j==1
handles.filename=handles.jpegFiles(j).name;
data1 = imread([handles.thepath filesep handles.filename]);
data2=imcrop(data1,[1 53 1392 52]);
imwrite(data2,'band2.JPG');
set(handles.text5_monitor,'String','band 2 created');
else
break;
end
end

The problem raise is that when it run, it only use display
>>band 1 created

it did't display band 2 created. infact it come up with an error saying
??? Reference to non-existent field 'text5_monitor'.

what i did it wrong?
