Hi all,

I have a set of data with some fields in the Attributes Table that default to <Null>.  If I edit a particular field, then try to set it back to a no data cell, the cell value is no longer <Null> but simply blank.  How do I change my field cell back to <Null> so I can run a query (for Null values) on it?  I am using ArcGIS for Desktop 10.1 SP1.
