i have one grouping called Group #1. I group on a field called asset code. The detail setion contains several lines for each asset code. I also created a subtotal field for each group. I want to use the drill down functionality so that when the report is first run the group name is shown and the subtotal. I want to give the user the functionality to drill down to view the details if the so wish. i right click on the detail section and click: Hide (drill down ok) but when i run the report the group with the subtotal is visible but i cannot drill down to the data for each group. i am new to crystal. please help!
