I would like to be able to compare a field value in one record in my data source to see if it equals the value of that field in the next record in my data source. I would like to continue this comparison till the field value changes. The goal is to extract into each PDF letter all the rows that have the same field value in column one. So...instead of variable information coming from one record, I want to combine variable information from multiple rows (records) where a specific field value is the same. Has anyone done this?
