I have one field that uses numeric codes to represent road classifications and another field that has the text description of the road class represented by the number in the first field. I'd like to link the two fields such that the text field automatically fills in the description data for the numeric field to simplify labeling in map legends. In my maps I'd like to use graduated color symbology based on the numeric classification of the road but automatically be able to display the description text from the text field in the symbology.
