Asp input search to display results

I am working on an ASP ecommerce website for a company and they expressed their desire to have the menu and everything up top to be created in flash. This includes a small search bar to search the site with. This is fine but I have never used flash to do this.

I would need to know what AS I would have to use in order to access the database (Access) and then reload a page and display the results. Should I even go this way or should I just do it in HTML as I planned originally?

Your attention and quick response is most appreciated. Thanks.
