Small modification to Magento website

Hi, I need a small modification done to my Magento based website.? Have a look at? [login to view URL]~zinnia/[login to view URL] At the moment there are three custom option for pricing that show up as a base price PLUS a certain amount on top of that. ? I need to modify the code so the custom options will show up the FULL PRICE.? So in this particular product the page will change **from** : ---------------- Basic price: ? ? $60? Options: Small: ? ? ? + $0 Medium: ? + $10 Large: ? ? ? +$20? ---------------- **to:** ---------------- Basic price: ? $60 Options: Small: ? ? ? $60 Medium: ? $70 Large: ? ? ? $80 ---------------- The change to the code has to be site-wide so it will apply for all the products (not just this one).? Please don't hesitate to contact me if you have any questions Thank you
