Trying to get one of my functions to automatically run when movie plays

Hey all,

I am having some difficulty getting a function to run/work when my movie plays.

The function controls my menu and I need one of the options to start flashing automatically when my movie plays.

In this case I am forcing the controlling variable to equal “1” so the first menu option should start flashing.

_root.menuvar = “1”; //controlling variable
_root.pt_menu.ptmenumc.menufinal.menuchange(); //running my function

It must be something to do with where I am running the function from or?

My file is here:

Any help would be great.
