Problem with Edit Text GUI

Question

Dear all, i'm working in GUI and i have a problem with an edit-text box. Y have program a function in a button, three parameter (or variables) for the function must be defined in three different Edit-text boxes, the inputs are all numbers.

I would like to define a default value on each text box, that can be changed if the user wants. The problem is that when i run the function (pushing the button) the values are not recognized and are changed by arbitrary values like 2.270087890625000e+02.

this an example of the edit text function that i'm using:

function difu_Callback(hObject, eventdata, handles)
% hObject    handle to difu (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 difu as text
%        str2double(get(hObject,'String')) returns contents of difu as a double
%set(handles.difu,'String','0.9');
handles = guidata(hObject);
difu = str2num(get(handles.difu,'String'));
handles.difuf=difu;
guidata(hObject, handles);

this is for difu (diffusion) something happens but the default values are not saved in the handles. (i'm creating this GUI using GUIDE) thanks for your help
