Hello I recently added this problem to a old Discussion in the comments but I am not sure it was the best place for it.
I've been trying to add audio to my Flash. Everything is running smoothly except when I click on a muteToggle and playPauseToggle button that are both placed on my stage. I have instance names for both of them. These are the Errors I get in my Output.
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Also here is my code in my main.as
