Hi guys!

here is a bit of my code from my matlab project, the function b and c are okay, but the resolve function seems, to be with a problem, it displays

Not enough input arguments.
Error in lay_out>resolve (line 129) X11 = handles.mydata.b * handles.mydata.c;  
function b1(hObject, eventdata, handles)
  b = str2double(get(hObject, 'String'));
  if isnan(b)
      set(hObject, 'String', 0);
      warndlg('Only numbers are supported', '!! Warning!!');
  end
    % Save the new b value
    handles.mydata.b = b;
    guidata(hObject,handles)
    end
    function c1(hObject, eventdata, handles)
    c = str2double(get(hObject, 'String'));
    if isnan(c)
        set(hObject, 'String', 0);
         warndlg('Only numbers are supported', '!! Warning!!');
    end
    % Save the new c value
    handles.mydata.c = c;
    guidata(hObject,handles)
    end
    function resolve(hObject,eventdata,handles)
      X11 = handles.mydata.b * handles.mydata.c;
      set(handles.x11, 'String', 1);
      end

We need to see the routine in which a reference is made to resolve()
