Hi, I summarized square footages for user area based on a table, then had to manually create text, adjacent to the legend, in the layout to get a project out the door.
It has been a while since I have used ArcMAP, but I recall there being some app that could summarize table data and add it to the legend label. Hopefully, I am not recalling something pre 10.0, or it was all a dream.
Any assistance you can provide will be great. Diana H
