GUI design problem: push button control a switch

Hi, everyone, I try to build a push button to control a switch in simulink model, however, I got this error :

??? Error using ==> @(hObject,eventdata)exe1('pushbutton1_Callback',hObject,eventdata,guidata(hObject)) 'pushbutton1_Callback' is an invalid option

??? Error while evaluating uicontrol Callback

in the M. file, I simply use set_param('name_/name','sw','0')

please help me . Thank you.

Post your function concerned with error

The error is with the pushbutton not the set_param command. You can see it cannot reference the pushbutton callback. This can happen for a number of reasons, one may be you changed the tag in GUIDE, changed the m-file and then saved GUIDE later and the m-file does not match the tag in guide. Could be something else...
