Component Height Report issue

I wrote a component height report that works, except it outputs multiple entries for each part. How can I get it to report just once for each part. Here is the report script.

# This is an extract command file
# generated by the Extract UI.
#
GEOMETRY
REFDES!=""
CLASS="PACKAGE GEOMETRY"
SUBCLASS="PLACE_BOUND_TOP"
OR
SUBCLASS="PLACE_BOUND_BOTTOM"
REFDES
REFDES_SORT
PACKAGE_HEIGHT_MIN
PACKAGE_HEIGHT_MAX
END
