Hi mwa,
Maybe I'm missing something, but I think you have two other
options without using a print time formula:
1-Group {yourgroupfield} and also put {yourgroupfield} in the details section. Suppress the group header. In the details section, format {yourgroupfield} by checking "suppress duplicates." Or,
2-Group {yourgroupfield} and in the format group section editor, check "underlay following section" for the group header section. Details will then print in line with the group header.
Just a thought (or two)--
