Help me on crystal reports

In crystal reports I have a Box in the one section which is designed to have a tabular look.I want to supress it when no data is found in the details.One section has the box and next section has lines for tabular look.By Supressing the section i was able to supress the section with lines .But the section with the box appears on the top.Is there any way to supress a section at runtime. ie any method that can be coded for supressing the section or any other way to do it ?

Thank You.

have you considered not sending the unwanted data to the report? ie..... figuring out using sql up front.... hey... there's no detail data.... so I'm not gonna send master data either. I use this technique a lot. Hope it helps
