Site buttons don't work (gallery with xml & flash)

Over the weekend, I tried out the tutorial of the photo gallery with xml and flash on this site (excellent tutorial, by the way!) since I need something like it for mine.

However, I placed it inside a movie clip. When the photo gallery runs, no buttons on my site (even those not inside the movie clip nor associated with the gallery) work.

Everything is exactly the same as the tutorial-- the code, the names of the buttons, etc.

I also tried adding the name of the movieclip (myMovieClip) in this part of the code:
[size=1][color=#0000d0]Key[/color].[color=#0000d0]addListener[/color]color=#0000ff[/color]; [/size][size=1][color=#000050]**myMovieclip.**previous_btn[/color].[color=#0000d0]onRelease[/color] [color=#0000ff]=[/color] [color=#006610]function[/color]color=#0000ff[/color] [color=#0000ff]{[/color][/size]
[size=1][color=#000050]prevImage[/color]color=#0000ff[/color]; [/size][size=1][color=#0000ff]}[/color]; [/size][size=1][color=#000050]**myMovieClip.**next_btn[/color].[color=#0000d0]onRelease[/color] [color=#0000ff]=[/color] [color=#006610]function[/color]color=#0000ff[/color] [color=#0000ff]{[/color][/size]
[size=1][color=#000050]nextImage[/color]color=#0000ff[/color]; [/size][size=1][color=#0000ff]}[/color]; [/size]
But the same thing still happens. I can’t figure out how to fix it. Can anyone help?

edit: nevermind. I figured it out: Flash MX 2004 is so buggy that I had to redo the buttons by duplicating another. I hope Flash 8 isn’t like that!
