I'm using a combination of data driven pages and a python script to populate text elements on a layout. I have a project set up with an index layer, and a mask layer. I also have a third layer (permits), which I have set up as a page definition query, to match the index layer selected (they both have a map_number field). This works as I scroll through the pages, the permits layer updates to show only those permits within the active page. I would like for those queried permits to then populate a table made up of two text elements.
Now, when I run though the script, the text elements are populated but not with correct information. As I change pages, and the queried permits change, I cannot get the related text elements to change/update. All the rows will show in the text element(s), and not the queried ones only. What am I missing here? I'm not sure if it is a definition query problem or a cursor problem (or neither of these)?
