HI,

i try add newfileld T.ID # 0 as below i get error message Field "ty2010" does not accept null values

and i need to T1.Nam = T.Nam get exactly nam , i try set exact on and == but not work
select T.ID,T.Nam, T.ID1, (select sum(Y2010) as YTD from NewTest T1 WHERE   T1.ID#0  AND T1.Nam = T.Nam and T1.ID1 <= T.ID1 ) as YTD from ;
   NewTest T into cursor crsYTD
     
   update NewTest set ty2010 = YTD ;
         from NewTest inner join crsYTD YTD on NewTest.ID1 = NewTest.ID1

local lnRecNo
lnRecno = 1
select NewTest
scan 
if between(m.lnRecno, 1, reccount('crsYTD'))

   goto lnRecno in crsYTD
   replace ty2010 with crsYTD.YTD &&error message Field "ty2010" does not accept null values 
   endif
   lnRecno = lnRecno + 1
ENDSCAN
