calculations on summary fields

[Lougee]

Is there any way to define a calculation that will add several summary fields together?

Yes, use the GetSummary function.

I tried that and it didn't work. So obviously I haven't the slightest idea of the correct syntax. I have 2 summary fields: A (which is the total of field ABC) and Z (which is the total of field ZYX). How do I get the sum of these 2 summary fields?

Thanks for your help.

The function doesn't work unless you have sorted by the field specified in the calc, in this example "breakField":

GetSummary(A;breakField) + GetSummary(B;breakField)
