Hazel Action to Run python script any time file is added

I'm trying to Have Hazel automatically run a script anytime I add a file to a folder. I've come up with this script below:

When I open the Hazel pref pane and choose "Run Rules Now" the script does indeed run successfully, but when I just add a file to the folder that has the Hazel action, it doesn't run. Any suggestions as to how to make the Hazel action trigger when a file is added to the folder?
