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.

          at info.mixnwithmarissa.cakecreater::Main/togglePlayPause()[/Users/stude nt/Desktop/MM461_Lab3_mpollocktest1/info/mixnwithmarissa/cakecreater/M ain.as:153]
