I've created a report that groups my entries by customer name.  I'm trying to suppress the top group/blank "cath-all" group and just can't figure this out for some reason.  This group that I am trying to suppress has data in the detail section but since none of these lines have a customer name specified in them it puts them in a group at the top without a heading, so it appears to be blank to me, therefore I though the following code would hide this group: 

 

Under the Details / "Suppress Code" Box Icon of the Section Expert, I've placed the following code and it doesn't do anything:

 

GroupName ({Job.Customer}) = ""

 

Can anyone please help?

Thank You!
