Error moving file: File is busy

Hi all,
I'm new to Hazel, so forgive me if this is a dumb question
I'm creating a rule that renames a file stored on my local drive then moves it to a network drive. All seems to be OK until the move part. The rule fails and the log says this:
I have tried manually performing the move in the Finder and there is no problem. Any idea what's going on? Thanks!
Paul
