Asunto: Virtuemart sending double conversion

[oscar_briz]

I did the following store:

http://www.tixinda.com.mx/otoch/

Everything works fine except that when the user choose a currency other than Mexican Peso in the final process when confirming the order, becomes the currency of the shipping again. That is:

- If I charge MXN$ 250 for shipping and is chosen dollar, shipping costs USD $ 32.50.
- During the checkout process the price of the cart is fine, but when the "confirm order"...
- The dispatch said that costs USD $ 0.60 ($ 32.50 pesos)

Urgeme help, hopefully someone can advise me ...
