Can anyone tell me how to list GBP amounts(above 25k) in a Crystal Report
when

the base currency amount arrives via a SQL query (with currency  and amount
fields)

but to get the GBP amount it is somehow linked to exchange rates in an
Access database (ODBC)?

I need to eliminate entirely the under 25k items  - to leave me with a
good-looking over 25k crystal Report.

Many thanks for any ideas .

Regards

Martin
