I have used this report many many times with no problems.  But today I can't get AR-K to print a summary  (with or without months)  All I get is the heading, no authorties and 00.00 dollars.    It works just fine when asking for detail.  
 
Summary worked last quarter, and the last 40 quarters.
I have not had an upgrade in several years... so that is not it.
I have restarted the workstation.  Tried different date variables, different codes, etc. .    
 
This is a very valuable report, as we remit to 20 or 30 small cities and counties.  
 
Any and all help appreciated.
