Thanks for your help. That seems to have worked well.

I wanted to ask, if I could, what is the recommended setting for admin/configuration/My Store/Language Selector? (Should the default language be based on the Store preferences, or the customer's browser settings?) Right now it is set to the Default: Store's default settings. Does that setting have any effect on PayPal?

Also, I see that on the PayPal checkout page there is a language dropdown selector (which is great!) but with a limited number of languages (English, French, Spanish & Japanese). Is it possible to add to that list?

Thanks again.
