I'm trying to set up a US$ bank account in Sage Line 50. The currency field in the bank record is greyed out so I can't change it from sterling to USD. I've tried making it each of the 3 types of bank account (cheque/cash/card), but they're all the same. I've set up an exchange rate in the "Currencies" section of the settings menu.
What am I doing wrong you clever people???
