I am working on a hydric soils layout, and I have a table showing the MUSYM and MUNAME attributes of the soils present on each page of my map series. I cannot figure out how to have not have duplicates of attributes that are the same. I've tried to look up what I can do to fix this, and I'm currently trying to "concatenate" using "summary statistics", but it is taking forever, and I'm wondering if there is a better/easier way.
