I am in need of assistance. I deleted a "column" in the attribute table and this column was essentially tied to everything. I realized immediately that I had made a mistake so I closed ArcMap without saving changes in order to not save my said mistake. I reopened ArcMap and I believe the column is there...however I am now receiving an error message "ArcMap Drawing Errors: A Column was specified that does not exist."
Can anyone provide insight as to what i need to do to restore the former configuration? Your insight and assistance is greatly appreciated!
