Can I use a formula based on a group value?
I want to base the total if the group value exists

DatePart ("d",{RECORDED_SERVICE.STARTTIME}) =10 )

But the above is based on detail which I surpress based on conditions

I thought maybe this would work but it doesn't  ...

GroupName (({RECORDED_SERVICE.STARTTIME}, "by minute") DatePart ("d",{RECORDED_SERVICE.STARTTIME}) =10 )


Thanks
Joe
