If you know how to create the Flash menu, just replace the display of the menu in header.asp with your Flash menu. If you are good at Flash you can make it somewhat dynamic and have it read a text file of the category menu options or active content pages and dynamically build the menu from your text. However since the menu is displayed on every page of the site, this can sometimes be slow. If you don't change your navigation very much, you're better off building the Flash with the menu options directly.

I am not real experienced with Flash but most people create their whole Flash menu directly in Flash, i.e. the text, graphics and links are all defined in Flash. But there is a way to create a Flash file where it can read text and/or graphics externally from the Flash file when running in a browser and display those. So if you created a Flash menu and wanted to change the text on the buttons or the links, you just change a text file and the Flash file shows the new information. I am not sure how to do this but if you search Flash forums, I'm sure you can find information. If you're menus won't change, it is easier to just build the whole meu in Flash without external references. As far as scripting, I think the only scripting in Flash would be setting up the links when you click on a menu button.

In the header.asp file (vs. 3.0), search for a line with this text:

<!--#include file="inc_catsmenu.asp"-->
