How do I display only 1 currency for price?

Hi
I just came across this wonderful Joomla extension and am managing to add some products and all. But its showing up with BOTH Euro and USD when I only want the latter. I did go to systems-> currencies and disable the publish and display of Euro? Why is it still showing up? What should I do so it only displays 1 currency? (USD)

Also does the free version provide currency conversion facilities?

In the config, you have the option "main currency". That option is set to EUR by default. Even if the main currency is unpublished, it will still be usable. If you change that option, the currency will disappear.

The free version provides currency conversion yes. You need to go to the System->Currencies in order to set your conversion rates.

That took care of it Nicolas. Thanks for your prompt answer
