I written the above code and execute well yesterday,but today while executing this code Attempt to reference field of non-structure array.
Attempt to reference field of non-structure array.
Error in signup>submit1_Callback (line 106) uname1 = get(handles.u_name,'String');
Error in gui_mainfcn (line 96) feval(varargin{:});

Please help me…..
