hi all, i want to create a formula for change my value from EUR into USD. FIELD1 (choice): EUR, USD FIELD2 (number): amount in EUR or USD Now, if USD is selected in FIELD1 following should happen: calaculate FIELD2*0,71 otherwiese the result is FIELD2. FIELD3 (calculated): =IF(FIELD1="USD", (FIELD2*0,71), FIELD2)) When I use this formula I get error message: The formula contains a syntax error or is not supported. Any idea? I´m using english version of WSS 3.0. Thank you, fiuman007
