Placeholder error message with InDesign Data Merge
We use data merge frequently, using the same Excel files and InDesign templates over and over. Over the past week or so, our merges have stopped working, and we get this attached error message. We have removed any placeholders in both InDesign and Excel that are not being used. We have tried creating various .csv files from Excel. What could we be doing wrong, our workflow has not changed. Thank you!
