Hi Wu,

Just try adding the header and footer from within the report desginer.
Then open the FRX/FRT as a table and see what records are added.
That way you can see the values for records indicating headers and footers and the values for each field they should contain.
I don't now it by heart anymore but what I recall is that groups always consist of two records. And then there is the sum of the height of all bands that still have to match.
