Hi.
I'm extremely new to Python and programming as a whole. I have written
a python script with the assistance of ESRI ArcGIS 9.2, which uses
Python 2.4.1, however, it gives me this error when I try to run it.
I've already posted at ESRI support, and I was hoping that Python
people could help me more.
I hope there is something simple I could do to be able to define the
object that it thinks is NoneType. Please when someone responds,
please treat me as an absolute novice.
Thank you,
Marisa
Here is my code:
