How to get and set ArrayData in PageFooter when more then one row exists

[xoristzatziki]

I have a BASIC macro that displays a report from a BASE app and reads and writes in some report footer cells.
Macro works OK if page footer contains only “one row” (1 label control and, next to it, 1 numeric textbox containing a “calculated running total” with same height). oData() = tbl.getDataArray() and oData(0)(1) = "has the value:" & oData(0)(3) tbl.setDataArray( oData()) work as expected. The label changes to “has the value:XXXX”

If the page contains controls in a second row then oData() = tbl.getDataArray() crashes the app. I created a simplified odb but I have no points to upload it.

By using tbl.getSupportedServiceNames(),.dbg_properties,.dbg_methods and many, many “try and error” methods I found that oCell = tbl.GetCellByPosition(s1,s2) , ``oText= oCell.Stringand oCell.String = “BLAHBLAH”` can read and write text.
