format output

Hi all ...
I have installed this module, and it works fine, except, the output of the price.
In my node-product.tpl.php i have following code:

print $node->role_prices[4]

I got this from the contemplate module.
When editing a product, in the price per role field i enter for example: 19,00
the output is: 19.00000.

How do i get the output the same as for example the default price field: €19.00

Thanks for any step by step help here!
Have a great day!
Pat.
