I have the following currency format problem for my customized invoices I send out from my PayPal account: Being located in Switzerland I have a Swiss regional set-up for the three languages German, French and English. I am able to switch between these languages, and it is possible to send out my customized invoices in any one of these three languages. In German and French an invoice in USD appears with the dollar amount separated by a '.' , but in English the decimal separator between dollars and cents is a comma ','. How can I change the comma to a decimal point? There seems to be no way to do it using the PayPal website.
