[Tutor] point distance analysis

Hi I am looking for suggestions to fix my script to add an additional field.

Here is the script that I used and it calculates the distances that I was
trying to get, but I need to create an additional field in my table that
identifies the classification of the near_field ID so that I can use the
various distances to do a spatial analysis by summing the inverse square of
the distance for each unique classification to get a weighted probability
to classify the unclassified points.

Thank you

R. Brooks
