#1 expression with negative numbers

[Anonymous]

Hi,

i don't know its a bug or not.
I try to design a report with 3 sums in a group.
1. All values with positive Numbers -> OK
2. All values (total) -> OK
3. All values < 0 -> Will not work
I try this:
if([DS1."BETRAG"] < 0,sum([DS1."BETRAG"]),)
but it won't work.
