r12 calculation Syntax

[#1]

Hi i am trying to achieve the following R12 Calculation starting from today.

however my statement is not working.

i have one variable which is my Sales amount $(vNettoFsg)

and vToday = today ()

is my syntax wrong?

=sum({$<(vToday -365))>},$(vNettoFsg)

[er_mohit]

Try this

sum(if($(vToday)-365,$(vNettoFsg)))
