I'm looking to use data driven pages to automate some of my workflow, and I'm almost there for the most part.
I have a layer (Chainage - 200m markers along a watercourse) that I'm trying to perform a Page Definition Query on, but with no success. The chainage layer and index layer both share a field ('system' - sort of an in-house code for the watercourse). However when I set that as my field to query on, I have no chainage features appearing at all. The problem is, I can see that the system number is the definitely the same in the chainage layer and the index layer as it is displayed on my map page via dynamic text.
