Dynamic Text and DDP Sub-Index

Discussion created by ConwayGISCoor on Dec 15, 2011
I have a mapbook with a main index layer for each page, but also have a sub-index layer that then splits the main index into 6 subsets (A1, B1, C1, etc...).
Dynamic Text is great for the main index layer for the pages, but also need to automatically label the sub sections on the side of the maps as well, but have not figured out a way to do this, if even possible.
Assistance or advice?
Right now mapbook is 44 separate maps, but would prefer to use the DDP for ease of use and updates.
