ERROR using OutputFcn - VarargoutNotCell

i have a mat file and a gui running smoothly on matlab command window but when i compiled it it shows an error saying:

{??? Error using ==> charms_OutputFcn
variable output array 'varargout' must be a cell array.
Error in ==> gui_mainfcn 248
Error in ==> charms at 40
MATLAB:VarargoutNotCell
Warning:1 visible figure(s) exist at MCR termination}

my line 40 is like this:

    {  [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});}

how can i resolve this , thanks .

Did you declare

varargout = cell( someLength, 1 );

before line 40? If so, please also include that code. Also, why are there {} around the entire line?
