Hello,
Hoping one of you crystal gurus out there knows what I'm doing wrong. I keep 
getting the error "a string is required here" when I try to turn the string 
casenumber into a number so it will sort correctly.
SELECT{?group} 
CASE 'LENDER' :{Constituents.AlphaSort}
CASE 'SECTION':{ExhObjXRefs.Section}
CASE'CHECK#': tonumber({ExhObjXRefs.CaseNumber});

Thanks in advance for any help!
