How can I format the localization of my currency?

Hi,

I am running ZenCart 1.3.9g and I have installed the Spanish localization. However, when I check the prices after any order the user see this: €10.50

How can I make so the user sees 10,50€ ? (notice that the currency is at the end and that there is a comma instead of a dot).

I have checked through the forum but I can't find any answer regarding this...

Thanks.
