Correct - the origins of this program go back many years, when there were few options for PayPal currency, so they are hard coded.
For those wishing to see prices in their own currency, there is a disclaimer:
"You are viewing prices in your chosen currency, instead of the site currency.
Those prices are an approximation only.
The final charge which appears on your account may vary slightly."
Then you go to PayPal and pay according to the site currency required for your products (not necessarily the customer's currency).
I've never had to worry about European countries since people tend to use the Euro.
For now, best I can do is add to the hard coded entries - please indicate which ones you wish added.
They can only be those that PayPal supports - NOK, SEK and DKK are all supported.
If only NOK SEK DKK are required, the attached file should be extracted and uploaded to:
Clearly I need to integrate the PayPal and Currency sections and cross link the default currency option, especially since someone now needs it
the change is a little complex so I need to carefully work out how I do it.
Eventually I can also provide for language options when entering the PayPal checkout - Norwegian, Danish and Swedish are available in PayPal.
