Thanks Jason for your reply,
What method(s) would you recommend to achieve the listed problems or if it's possible at all?
I have a few questions on the best way to accomplish this task...
1. I intend on doing the exchange rate math for US$ in a new column in the database...how would I allow the ".com" extension access to that price list and not the ".ca" extension?
2. Is it possible to list "US$" dollar format in ".com" and "CAD$" format in ".ca"?
3. How would I add a icon at the top right of my page for the country currency flag for the customer to choose?
