Problems running python script from motion

I'm trying to set up the raspberry pi with my webcam as a motion detecting cctv that uploads the videos to google drive using [Jeremy Blythe's script](http://jeremyblythe.blogspot.co.uk/2012/06/motion-google-drive-uploader-and.html) I have motion working correctly and the python script runs when I test it from the terminal. However the script doesn't run when I add it to the on_movie_end option in motion.conf. The script I am using in the file is On_Movie_End /etc/motion/uploader.py /etc/motion/uploader.cfg %f I have also tried getting the on_movie_end to run a bash script that runs the python script and this doesn't work either. I am new to linux though so not entirely sure I have it correct. The script is: #!/bin/bash VIDEO=$1 /etc/motion/uploader.py /etc/motion/uploader.cfg VIDEO In motion.conf /etc/motion/uploaderscript.sh %f
