Error message with string

I was wondering what I receive the following error:
Error using hg.root/set
The name 'String' is not an accessible property for an
instance of class 'root'.
Error in test>reset_Callback (line 1352)
set(handles.value,'String','0');
Error in gui_mainfcn (line 96)
feval(varargin{:});
Error in test (line 114)
gui_mainfcn(gui_State, varargin{:});
Error in
@(hObject,eventdata)test('reset_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback
I'm not sure how it arose, the feature used to work.

Your "handles.value" contains 0. You have not shown us enough for us to be able to guess why that is so.

That would only be the reason if you then wrote "value" into handles.value .
You might want to do some renaming so that the location you display to makes clear in its name that it is a control rather than a numeric field. You might also want to have a field in handles that contains the latest copy of the string converted to numeric form; whatever name you use for that, make sure you will not confuse field entry with the name of the field for the static text. For example, handles.etabox and handles.etaval . Once you do that and start going through the code, any inconsistency treating the field as a control vs the numeric-conversion should become clear.
