hi,
i try as under, it works, i try to do it inside mygrid

a=SUBSTR("abc800",4)&&field(Sticket)char type
b=SUBSTR("abc500",4)&&field(Eticket)char type
c=VAL(a)-VAL(b)     &&field(noofticket)numaric type
? c

PS Why did you get rid of your photo?I'm going fat now so...
thanks

>Any help with what? You surely know you can't subtract a char field from another? - you'll get oprator/operand mismatch.
>Furthermore, the line "NOOFTICKET= Sticket- Eticket=60" is like saying subtract a logical field from a char field, as Eticket=60 would yield .F. even if you DIDN'T get oprator/operand mismatch.
