I am trying to use the data driven scale for a project I am working on and it does not seem to be working. I am working on a Fire Department Box book and the data driven pages are set to be based on the box boundaries. I added another column to the box boundary attribute table for the scale and put in what I wanted each page to be scaled at ex: 3600 or 4800 etc. When I set the scale to be data driven and use that attribute it does not change the scale to what I set it for. What am I doing wrong?
