Wasn't sure how to name this post...
I have a geodatabase with multiple feature datasets, each containing multiple feature classes of various polygon, line and point geometry type. Every polygon fc has a 'areaSize' field that I need to populate with square feet (all of the fds are in State Plane feet).
I think I'm getting close here, but still getting an error. (Eventually I will expand this to perform a similar calculation for length of line fc types as well.
The error I receive is attached. Any help is greatly appreciated.
Thanks.
