Error opening IDLE on Mac OS X 10.6

When I try to open IDLE as instructed on page 11 I get an error message.

It depends on which version of Python you're running, but if you've installed the latest (3.4.2), then instead of putting the following in Automator:

open -a "/Applications/Python 3.4/IDLE.app" --args -n

Try putting this instead:

/Library/Frameworks/Python.framework/Versions/3.4/bin/idle3.4 -n

The reason the text in the book doesn't work is a difference between Automator in versions of OS X prior to 10.7 (I believe 10.7, anyway) and later versions of the operating system.
