Hi Eike, Working with ranges inside the functions is not the issue, but registering function is. I followed steps described in http://wiki.services.openoffice.org/wiki/Calc/Implementation/Spreadsheet_Functions, and it seems that some additional changes must be made for functions that take range as a parameter.
