Please include the full and exact error Traceback, and remember to do so in the future. > I wrote this script on a box with Python 2.6 and it worked fine. > Moving it to a box with 2.4, and I get this error.

I would guess that `uidString` is probably an empty string or list, thus when you try to access the first character or item of it via uidString[0], you get an error. However, as you didn't include a Traceback, I can't be sure. I have no idea why the error only shows itself for certain Python versions; the problem is probably in some part of the code you're not showing us.
