- How about this: create a field "C" that has the data you'll put into your
- calculation field if "A" and "B" are empty. Then define your CalcField
- with:
-
- CalcField = if ((A = "") and (B = ""),C,A+B)
-
- I've done something similar in a database here. I then make C a non-printing
- object in the layout definition, so that only the CalcField is printed.
