Removing audio from imovie 09'

Hi,
I've read and watched the tutorials on how to do this but for some reason is not working on my comp. I want to extract just the audio from a mov clip so that I can edit it in garageband. I select the entire clip, detach audio, and then it has the purple bar underneath the video clip that your supposed to be able to move freely but for some reason will not move for me. I click on the bar and try to move but nothing happens....Any ideas?? Its kind of frustrating especially when you watch how easy it is on the tutorial! Thanks

Try importing the movie directly into Garageband. It will automatically separate the audio from the video.
