Delete local users script

Greetings:

I'm running some labs in our Journalism Department, using Apple Remote Desktop for quarterly updates, en masse.

There is a script that I've borrowed from the following post, which was written by one Thomas Larkin...

https://discussions.apple.com/thread/2519798?start=0&tstart=0

I ran the script in Lion, and it seemed to be fine.

But now running it in Mountain Lion, even as "root," I get the following:

Error: -71 "Delete. Invalid Path."

I'm not a coder, so I'm hoping that someone can take a look at the script and sort out what needs to be modified in order for it to work as expected.

Any assistance would be greatly appreciated; thanks, so much!

Best,

Velanche Stewart
