Dear all DW experts - please advise - even if it is brief

BACKGROUND FACTS:

1. I have a basic html website that I created which lists prices for products for sale.

2. The store sells products overseas to Australia.

3. When the Aussie dollar rallies I must lower my prices in order to remain competitive.

4. Prices / database is on a excel spreadsheet. The spreadsheet has the exchange rate in cell A1 - when I can change this, all prices in the spreadsheet are update automatically.


PROBLEM:

1. What is the best way to set up the website so that prices can be updated quickly if not automatically

2. Which server technology (ASP, coldfusion) would be best?


Thanks in advance for any guidance offered.


Regards,

David.
