- For %%1, you forgot the word 'callback' and you were trying to assign the callback to the buttongroup itself, not the buttons. The alternative would be to use the selectionchangefcn of the buttongroup.
- For %%2, you used the field data2, but never assigned a field data2. Also, you do not need to use FINDOBJ here, you could replace this with varargin{1}.
- For %%3, you referenced N.figure, but there was no field with this name in N. You meant N.fh.
