     Posted: 14 Feb 2013 at 11:00am
Hello,
 
I have a formula field on a group header which does a datediff.
Both dates are on the report and the datediff is fine for all records, exept for the first record, the field is zero instead of 25.
 
have tried whileprintingrecords; and onfirstrecord; in the formula, but it doesn't solve the problem.
 
Any ideas ?
 
thanks

onfirstrecord;
whileprintingrecords;
 
local datetimevar d1:= {startdate}
local datetimevar d2:= {enddate}
 
datediff("D", d2, d1)
 
result :
startdate               enddate           diff
2012-12-08          2013-01-02     0
2012-12-08          2013-01-02     25
2012-12-09          2013-01-02     24 
2012-12-23          2013-01-08     16

the on firstrecord is not needed. it only references the first record in the report, not the group.
You should just be able to use the below and place in the group header to display the rsult of the first row.
 
datediff("d", {startdate}, {enddate})

I finally found the real problem.
The start date is a variable passed on from a subreport.
 
The subreport was in the same section as the rest of the fields.
 
I inserted a section on the GH. Copied all the fields into GHb and left the subreport on GHa.
 
problem solved !
