Showing of 2 currencies in product page - urgently

Hi everyone!

As a video games export fulfillment business, we’re trying to upload my pricelist from supplier A,B,C all from different countries.

But We face a problem, they are all quoted in their own currencies…

Is there anyway we can mod the cart on our own – which file to go to… so that the product page reflects this:

  1. Source Currency Amount – only changes when price from supplier changes…
  2. Payment Currency Amount (to be converted to the currency used in Cs-Cart automatically).

    Need to launch my site by next Monday and we have not uploaded those pricelists!

    Thank you.

help anyone?
