This code is working fine when i run it as a script file .. and gives the following error if i run it as a function, error is: ??? Error while evaluating TimerFcn for timer 'timer-1' Error using ==> timer.get at 46 Invalid timer object. This object has been deleted and should be removed from your workspace using CLEAR. what do i do now?? Ashwini
