I created this ad and set currency as Canadian Dollars ...
I can see anywhere in the displayed ad for other members where it shows the dollar amounts are Canadian dollars? Shouldn't there be a currency field displayed after the amount?
Well if your referring to actual currency calculations as far as what is charged I believe thats handled by the actual payment site. For instance if you pass the canadian price a user puts on the ad to paypal and your paypal account is set for US you payment on the ad should get calculated based on paypals current conversion rates.
