Hi, I got CS4 for Cristmas, and I am having trouble with my buttons. I have a button on each frame programmed to go to the next frame when I click it. All of the buttons worked fine until I put a movie clip on frame 12. Now when I click to get to frame 13, it goes back to frame 7. This is what it says in the output:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Can anyone help me to fix it please? I don’t have a clue what any of it means. Thanks
