Prices change automatically

[euforico]

HI friends!

 

Today a friend told me a question and i don't if possible on Oscommerce. The store is working with Chilean peso, but all the day the "store admin" will modify the prices because the USD Dollar had changed.

 

My idea is:

Publish all the precios in USD dollar in the store and the system will make the following multiplication:

 

PRICE IN DOLLARS * DOLLAR VALUE

 

"Dollars value" can be a unique central input how can introduce the value dollar. For example if i change the value of "DOLLAR VALUE" all the prices will chage.

 

Somebody know how can do this? if exist some contributions?

 

THANKS!
