I have a form that allows people to place order and limit price that they want to buy in advanec. For example, today is 11/09/2004. Customer can place the limit price that they want to buy the product. For example they place the limit price at 12 and today the price of product is 20.

What I want to do is if the price of product doesn't reach the limit price that was set by customer within 3 days , I want that order is terminated . However, if the price reach the price that is set by customer I want to execute program.

Anyone have any idea how to do it. Do I need to use cooky !!!

What database platform do you use?

I use Microsoft Access 2000 and ASP

Access has no built in functions for automation. You'll either need to write something separate in another language (C++, VB, etc) which does the work and schedule that app with the OS to run regularly, write an ASP page that does your work and refreshes regularly (which requires you have a browser on some computer running this page 24/7), or you upgrade to a DB that has a built-in scheduling mechinism (such as MS SQL Server 2000).
