Create a new file named toggle1_Callback.m with the following content

   function toggle1_Callback(varargin)
     fprintf(2, 'toggle1_Callback reached\n');
     fprintf(2, 'Number of arguments: %d\n', nargin)
     for K = 1 : nargin
       thisarg = varargin{K};
       fprintf(2, 'Argument #1 is class "%s"\n', class(thisarg) );
       argsize = size(thisarg);
       fprintf( 2, ['and size [', repmat('%d, ', 1, length(argsize)-1), '%d]\n'], argsize );
     end
     fprintf('Now we are going to deliberately error in order to find out who called us\n');
     error('Report the above and the trace to MATLAB Answers');

Then execute and report to us everything that showed up in red.
