Problems with removeChild()

programming flash
1

Greetings

I have a main movieclip called pageWork from which I am openeing another (in the future several) movieclip. This movieclip is galled galleryPhoto. This works fine.

However when I try to remove this movieclip I get this error:
TypeError: Error #1010: A term is undefined and has no properties.
at pageWork/frame1()

Here is the ActionScript in pageWork frame 1:

I know that in the future I should remove the addEventListener also, but I really just want to get this part working. I’m really confused as to why it isn’t.

p.s. I’ve also tried this.removeChild(photoGallery); with similar results.
