Currency code (for checkout system) how do you change it to £

Currency code (for checkout system) how do you change it to £, also what would be the text for £, at the moment i have "$" for euro?

Thanks In Advance....

Do you want change existing or add new payment code?

either would work,  I dont have the option for £ in the dropdown menu, just dollars and euros.,

hello open the - modules\boonex\payment\install\sql\install.sql find there this code line:

('pmt_default_currency_code', 'USD', @iCategoryId, 'Currency code', 'select', 'return strlen($arg0) > 0;', 'Cannot be empty.', 0, 'AUD,CAD,EUR,GBP,USD,YEN'),

and replace with:

('pmt_default_currency_code', 'USD', @iCategoryId, 'Currency code', 'select', 'return strlen($arg0) > 0;', 'Cannot be empty.', 0, 'AUD,CAD,EUR,GBP,USD,YEN,Your_currency'),

reinstall module!
