I am having an issue with an Index Error. When I try to run a 'Nearest Neighbor Analysis' or a 'Calculate Distance Band from Neighbor Count', I get the error Index out of range. I have tried changing just about every input variable. I have tried creating a new shapefile so that I would not have to use a definition query, or a database. The only thing that seems to be successful is using a different computer, which makes me concerned that it's my computer. I tried transferring a new NearestNeighbor.py file in case mine was corrupted but I have not been able to resolve the issue. Any suggestions would be welcome.
