Pound Sterling not working in Opencart

Question

I'm having issues with the Pound Sterling £ currency in Opencart (I use OC 1.5.1 and my payment gateway is Authorize.net). When a customer attempts to submit their order on the checkout page of my site with the Pound Sterling currency selected they receive this message:

The page at https://mysite.com says: The supplied currency code is either invalid

How do I resolve this to allow customers who use the Pound Sterling to check out? I'm having trouble finding information about if this would be an issue with Opencart or with my payment gateway which is Authorize.net.

As far as I knew, the currency selector in Opencart is purely for informative purposes for the customer, because when they submit their orders the currency is automatically converted to USD $ and sent to Authorize.net for processing. Correct me if I'm wrong about this though?

Is there some kind of code that I need to edit/place into my Opencart to resolve this?

Thanks for your time !! I really appreciate any help with this!

I've discovered that Authorize.net is restricted to which country you operate your company from (https://support.authorize.net/authkb/index?page=content&id=A414). So for a company in the US you can only process CAD or USD thru Authorize.net.

I'm going to use Paypal for international (EURO, Pound Sterling) and Authorize.net for USD orders.
