I added a Field called "Plasticity_String" to the Atterberg table, and I can't get the field to populate. I can populate/import the same data from my Source Lab Specimen table to my target Lab Specimen table, but not to this new field "Plasticity_String" that I added to the Atterberg table. Is the Atterberg table locked against adding additional fields? Im kind of new to the correspondence files and trying to also learn.
