I sell products on my site, and on this page: http://www.lights4yourpc.com/buy.html I want to make it count down how many are left in stock automatically, and display a different page when there are none left in stock. Once the contact form is sent, the visitor is redirected to another page, so I need it so that it counts down each time someone visits that page. I also need to be able to manually update the number left in stock when new stock arrives. I have absolutely no idea of how to do this, but I assume I will need databases and PHP and stuff. You will have to explain in detail exactly what I need to do as I know nothing about PHP and databases. I will pay generous credits to whoever gets this working for me.
