I'm not sure - but from your post I think that Button2,1 has prontoscript on it, and you are trying to run that prontoscript from somewhere else by calling executeActions()?

If so - you can't do that. You cannot execute a buttons prontoscript from anywhere except when the button is pressed.

If that is what you are trying to do, you have two choices. The easy (but bad) way :

Copy the prontoscript from that button to your movie button.

The harder (but good way) :

Move the prontoscript for Button2,1 somewhere else (e.g. at an Activity level) wrapped inside a function - and call that function from the Movie button and from your existing dynalite button.

Obviously option 2 only works if your movie button and your dynalite button are on the same device / activity. If they're not, you really may as well just copy the button script.
