Thanks Jaydee, but's not what I'm looking. Let me explain a little, the report is grouped by CAR MAKE and bellow each car make I have replacement parts for different models. OK? what I need is to write a list (model1, model2, ...) that will be printed right bellow the group header, before the detail. Is a big automobile parts catalog and what's intended is that before going to the detail, you can see in a glance if the company have at least one part for that specific model.
This is what I mean:
Group: Chevrolet Passenger Car
Beretta, Cavalier, Celebrity, Citation, Corsica,
Impala, Lumina & Monte Carlo
Detail: 01-92 Malibu........... 887636
01-94 Cavalier......... 765777
97-90 Citation......... 836363
etc....
