Hello Max,

The expression would be: calculate()

(you need the parenthesis)

I don't know if I would call it calculate though, because that is a reserved word. Make sure the program file is in your path (or in the current directory), or you can use the SET PROCEDURE TO myprogram ADDITIVE before running the report.
