new user help

hi,
I want Hazel to read my SD card, which contains .NEF, .MOV and .xmp files and upload them to a folder in my dropbox
called NEFfiles.I also wanted them tagged red and want a notification when Hazel completes the task.I tried using if any of the conditions are met:Extension Is .NEF,MOV and .xmp.but it did not work.if you could help I would appreciate it.

Are you trying to fit all those into a single condition? If so, it won't work. You need to use separate conditions for each case.
