So with some geodatabases - specifically this one I've been using from converted KML's - I can calculate fields, even just something simple as calculating a new field as one of the older fields, using VB but not Python, is there something up with the geodatabases - like any idea on why this might happen? I've tried a ton of simple expressions and only VB Field Calculations work and Python Expressions don't in these particular geodatabases.
