I am using Zen Cart 1.3.8a and just an issue with currencies.

A customers was setting the shop currency to A$

The generated invoice was in $ - but was in fact A$ but the "A" not mentioned.

The customer then paid Paypal with US$

That order got stuck since Paypal amount and invoice amount were not matching.

It would be great if the invoice could mention the currency, and always also a conversion to a base currency, in my case US$

Is there a way to do that?
