error exporting smallworldness

Hi! Thank you so much for your wonderful program!! 

I am currently having difficulty when I ask GraphVar to calculate smallworldness using random networks. It seems to run well until the final step of exporting the variables; then, I get the following error:
Index exceeds matrix dimensions.
Error in GraphVar_CalcExport_Callback (line 66)
                if(sum(size(Result{1}) > 1))
Error in gui_mainfcn (line 95)
Error in GraphVar (line 40)
    gui_mainfcn(gui_State, varargin{:});
Error in
Error while evaluating uicontrol Callback
Do you have any thoughts about what I might be doing wrong? I am new to matlab so have had difficulty troubleshooting this myself. Thank you!
