asp headache

i am trying to develop a asp shopping basket for a university project, i have used phpmyadmin to create the database with products etc and am usinf asp to show the list of products all of which works fine. The problem i have is that by each product i have a BUY link that when clicked i want a new page to load displaying the selected product with its info and price etc and on this new page i want the user to be able to enter the quantity required and then when the submit order button is clicked i need the database to be updated (the product selected to be deducted from the total products section of my database) and a new table created that will show what has been ordered etc. Any ideas
