Assign timer function from another file to global object

I have a global audioplayer object that is used by two different GUIs.

GUI1.m

global ap;

% functions and stuff... 

function toBeCalled(obj, evt, a)
  % Timer function for ap

GUI2.m

global ap;

function assignTimerFcn()
  % set the TimerFcn for ap
  ap.TimerFcn = {@toBeCalled, 2};

I get an error message stating that the function doesn't exist when I play the audioplayer object if the TimerFcn is set this way.

Is there something else I need to specify in order to tell Matlab that I intend to use the toBeCalled function from GUI1.m instead of looking for a toBeCalled function in GUI2.m?

Thanks

If the "toBeCalled" function is a subfunction of the GUI1.m file, you cannot access it directly from anywhere else. Move "toBeCalled" in an own M-file to allow this.

This is not a problem of timers or guis, but the wanted behavior of subfunctions.

Thanks, I'll give that a go
