Hazel and dropbox/removable drives

Hi there,
I've set up a rule that moves files to a dropbox location (stored on a removeable drive) on my mac, let's call it folder 1. However, I'm running this rule on two computers, both of which have this dropbox location on different removable drives. Therefore, whenever I open the rule on computer 1, after having run it on computer 2, there's a red cross next to the folder and the path is greyed out (and I have to go in and manually change it). And vice versa.
Is there a workaround for this/best practice for dealing with removable drives/dropbox? Thanks for any tips.
Incidentally, it would be very useful to be able to upload images directly to the forum/board, I know you can link, but it's not quite as convenient.
Mike
