Current nav button in active state

Greetings kirupa people,

Can anyone explain how I would replicate the navigation on the following site: www.8dd.co.uk

It’s very simple I know (like me with ActionScript!) but I have trawled the forums and can’t find anything similar that I have managed to successfully work out for myself. For those that haven’t looked at the example it is a menu with normal (grey text) and rollover/active states (red text). The current selected option should be disabled and on the active state until another option is selected. This serves to tell the viewer where they are without repeating it elsewhere.

Should this be a movieclip or buttons? Do I need framenames and actions to move the timeline?

Any help much appreciated oh wise ones… :rocker:

Paul
